A nurse is caring for a client who is scheduled for an exercise stress test. Which of the following comments made by the client should indicate to the nurse that the client requires further teaching?
A. "I'll skip my coffee the morning of my test."
B. "I'll take my heart medications the morning of my test."
An exercise stress test is a diagnostic procedure that measures the heart's response to physical activity. The client is instructed to walk on a treadmill or pedal a stationary bike while their heart rate, blood pressure, and electrocardiogram are monitored. The test can help detect coronary artery disease, arrhythmias, or other cardiac problems. The client should follow certain guidelines before the test, such as: Avoiding caffeine, nicotine, alcohol, and stimulants for at least 4 hours before the test, as they can affect the heart rate and blood pressure. Fasting for at least 2 hours before the test, as eating can affect the blood flow to the heart. Getting adequate rest and sleep the night before the test, as fatigue can affect the performance and results of the test. Wearing comfortable clothing and shoes that are suitable for exercise. Informing the provider of any medications they are taking, as some medications may need to be withheld or adjusted before the test, such as beta blockers, calcium channel blockers, nitrates, or antiarrhythmics. These medications can affect the heart rate and blood pressure and interfere with the interpretation of the test results. Therefore, the comment made by the client that indicates a need for further teaching is "I'll take my heart medications the morning of my test." The client should consult with their provider about whether they should take their heart medications or not before the test. The other comments made by the client are appropriate and indicate that they understand the pre-test instructions.
C. "I'll get 8 hours of sleep the night before the test."
D. "I will not smoke prior to my test."

A nurse in a cardiac care unit is caring for a client with acute right-sided heart failure. Which of the following findings should the nurse expect?
A. Increased pulmonary artery wedge pressure (PAWP).
Increased pulmonary artery wedge pressure (PAWP). This statement is incorrect because it describes a finding of left-sided heart failure, not right-sided heart failure. Left-sided heart failure is a condition in which the left ventricle fails to pump blood effectively to the systemic circulation, causing a backup of blood in the pulmonary circulation. This leads to increased pressure in the left atrium and the pulmonary capillaries, which can be measured by the pulmonary artery wedge pressure (PAWP). A normal PAWP is 6 to 12 mm Hg, but in left-sided heart failure, it can rise above 18 mm Hg. Symptoms of left-sided heart failure include dyspnea, orthopnea, paroxysmal nocturnal dyspnea, crackles in the lungs, and pink frothy sputum.
B. Elevated central venous pressure (CVP).
Right-sided heart failure is a condition in which the right ventricle fails to pump blood effectively to the lungs, causing a backup of blood in the systemic circulation. This leads to increased pressure in the right atrium and the vena cava, which can be measured by the central venous pressure (CVP). A normal CVP is 2 to 6 mm Hg, but in right-sided heart failure, it can rise above 10 mm Hg. Symptoms of right-sided heart failure include peripheral edema, jugular venous distension, hepatomegaly, ascites, and weight gain.
C. Decreased brain natriuretic peptide (BNP).
Decreased brain natriuretic peptide (BNP). This statement is incorrect because it describes a finding of normal or reduced cardiac function, not heart failure. Brain natriuretic peptide (BNP) is a hormone secreted by the cardiac cells in response to increased stretch and pressure in the ventricles. It acts as a diuretic and a vasodilator, lowering blood volume and blood pressure. BNP is used as a biomarker for diagnosing and monitoring heart failure, as it reflects the degree of ventricular dysfunction. A normal BNP level is less than 100 pg/mL, but in heart failure, it can rise above 400 pg/mL.
D. Decreased specific gravity
Decreased specific gravity. This statement is incorrect because it describes a finding of dilute urine, not concentrated urine. Specific gravity is a measure of the concentration of solutes in urine, reflecting the ability of the kidneys to regulate fluid balance. A normal specific gravity is 1.005 to 1.030, but it can vary depending on fluid intake and output, hydration status, and renal function. In right-sided heart failure, fluid retention and reduced renal perfusion can cause oliguria and increased specific gravity of urine.

A nurse is performing discharge teaching for a client who has seizures and a new prescription for phenytoin. Which of the following statements by the client indicates a need for further teaching?
A. "I'll be glad when I can stop taking this medicine."
Phenytoin is an anticonvulsant medication that is used to prevent and treat seizures. It works by stabilizing the electrical activity of the brain and reducing the spread of abnormal impulses. Phenytoin is usually taken for life or until the seizures are controlled by other means, such as surgery or diet. The client should not stop taking phenytoin without consulting their doctor, as this can cause withdrawal symptoms or increase the risk of seizures.
B. "I have made an appointment to see my dentist next week."
"I have made an appointment to see my dentist next week." This statement is correct because phenytoin can cause gingival hyperplasia, which is an overgrowth of gum tissue that can lead to bleeding, infection, or difficulty chewing. The client should practice good oral hygiene and see their dentist regularly to prevent or treat this condition.
C. "I will notify my doctor before taking any other medications."
"I will notify my doctor before taking any other medications." This statement is correct because phenytoin can interact with many other medications, such as antibiotics, anticoagulants, oral contraceptives, or antacids. These interactions can affect the blood levels and effectiveness of phenytoin or the other medications, causing adverse effects or reduced seizure control. The client should inform their doctor of any other medications they are taking or planning to take, including over-the-counter, herbal, or dietary supplements.
D. "I know that I cannot switch brands of this medication."
"I know that I cannot switch brands of this medication." This statement is correct because different brands of phenytoin may have different formulations or bioavailability, which can affect the absorption and metabolism of the drug. Switching brands can cause changes in the blood levels and effectiveness of phenytoin, leading to toxicity or reduced seizure control. The client should always use the same brand of phenytoin and check with their pharmacist if they notice any changes in the appearance or labeling of their medication.

The other options are correct and indicate that the client understands the discharge teaching because:
- "I have made an appointment to see my dentist next week." This statement is correct because phenytoin can cause gingival hyperplasia, which is an overgrowth of gum tissue that can lead to bleeding, infection, or difficulty chewing. The client should practice good oral hygiene and see their dentist regularly to prevent or treat this condition.

A nurse suspects a client who has myasthenia gravis is experiencing a myasthenic crisis. Which of the following interventions should the nurse take?
A. Administer an anticholinesterase medication.
Administer an anticholinesterase medication. This statement is incorrect because anticholinesterase medications, such as pyridostigmine or neostigmine, are used to treat the symptoms of myasthenia gravis by inhibiting the enzyme that breaks down acetylcholine, which is the neurotransmiter that stimulates muscle contraction. However, these medications can also cause a cholinergic crisis, which is another complication of myasthenia gravis that occurs when there is too much acetylcholine in the neuromuscular junction, causing muscle weakness and paralysis. The nurse should not administer an anticholinesterase medication without confirming the cause of the crisis, as this can worsen the condition and mask the signs of respiratory distress.
B. Instruct the client to perform the pursed lip breathing.
Instruct the client to perform the pursed lip breathing. This statement is incorrect because pursed lip breathing is a technique that helps to slow down and control breathing, reduce air trapping, and improve gas exchange. It is used to manage chronic obstructive pulmonary disease (COPD), asthma, or anxiety. It is not helpful for a client who has a myasthenic crisis, as their respiratory muscles are too weak to maintain adequate ventilation, regardless of their breathing patern.
C. Prepare to administer a vasoconstrictor.
Prepare to administer a vasoconstrictor. This statement is incorrect because vasoconstrictors are medications that narrow the blood vessels and increase blood pressure. They are used to treat hypotension, shock, or hemorrhage. They are not helpful for a client who has a myasthenic crisis, as their problem is not related to blood pressure or blood flow, but to respiratory muscle weakness and inadequate ventilation.
D. Prepare the client for mechanical ventilation.
This is correct Myasthenia gravis is a chronic autoimmune disorder that affects the neuromuscular junction, causing weakness and fatigue of the voluntary muscles. A myasthenic crisis is a life-threatening complication of myasthenia gravis that occurs when the respiratory muscles become too weak to maintain adequate ventilation. Symptoms of a myasthenic crisis include severe dyspnea, cyanosis, tachycardia, tachypnea, and hypoxia. The nurse should prepare the client for mechanical ventilation.
Full Explanation
Choice A reason:
Administering an anticholinesterase medication is not the primary intervention during a myasthenic crisis. While these medications can improve muscle strength in myasthenia gravis, they are not sufficient in the event of a crisis.
Choice B reason:
Pursed lip breathing is a technique used to manage dyspnea but is not adequate for the acute management of a myasthenic crisis, which can involve respiratory muscle paralysis.
Choice C reason:
Vasoconstrictors are not used in the treatment of myasthenic crisis. This condition is not related to vascular issues but to neuromuscular transmission failure leading to respiratory failure.
Choice D reason:
Mechanical ventilation is the correct intervention as it provides the necessary respiratory support when the patient's respiratory muscles are too weak to maintain adequate ventilation.
