The nurse is reviewing the laboratory test results of a client with long-standing hypertension. Which result would be of most concern to the nurse?
A. Creatinine 3.2 mg/dL
This is the most concerning result for the nurse. Creatinine is a waste product of muscle metabolism that is filtered by the kidneys and excreted in the urine. A high creatinine level indicates impaired kidney function, which can be a complication of hypertension. The normal range of creatinine is 0.6 to 1.2 mg/dL for men and 0.5 to 1.1 mg/dL for women. A creatinine level of 3.2 mg/dL is more than twice the upper limit of normal and suggests severe kidney damage.
B. Potassium 3.4 mEq/L
This is not a concerning result for the nurse. Potassium is an electrolyte that is essential for the function of nerves and muscles, especially the heart. The normal range of potassium is 3.5 to 5.0 mEq/L. A potassium level of 3.4 mEq/L is slightly below the normal range, but not enough to cause serious problems. A low potassium level can be caused by diuretics, vomiting, diarrhea, or excessive sweating. The nurse should monitor the client's potassium level and symptoms, and advise the client to eat foods that are high in potassium, such as bananas, oranges, potatoes, and tomatoes.
C. Hemoglobin 12.8 g/dL
This is not a concerning result for the nurse. Hemoglobin is a protein in the red blood cells that carries oxygen to the tissues. The normal range of hemoglobin is 13.5 to 17.5 g/dL for men and 12.0 to 15.5 g/dL for women. A hemoglobin level of 12.8 g/dL is within the normal range for women and slightly below the normal range for men, but not enough to cause significant anemia. A low hemoglobin level can be caused by blood loss, iron deficiency, or bone marrow disorders. The nurse should assess the client's history, diet, and symptoms, and check for other signs of anemia, such as pallor, fatigue, and shortness of breath.
D. Blood urea nitrogen (BUN) 20 mg/dL
This is not a concerning result for the nurse. Blood urea nitrogen (BUN) is a waste product of protein metabolism that is filtered by the kidneys and excreted in the urine. A high BUN level indicates impaired kidney function or dehydration. The normal range of BUN is 7 to 20 mg/dL. A BUN level of 20 mg/dL is at the upper limit of normal, but not enough to indicate serious kidney problems. The nurse should ensure that the client is well hydrated and monitor the client's urine output and specific gravity.

Similar Questions
A client with alcoholism is admitted to a medical-surgical unit with a serum magnesium level of 0.9 mEq/L. Which clinical manifestations would the nurse expect to find in this client?
A. Tremors and twitching
This is the correct answer. Tremors and twitching are signs of hypomagnesemia, which is a low level of magnesium in the blood. Magnesium is a mineral that is involved in many enzymatic reactions and neuromuscular functions. A low magnesium level can cause hyperexcitability of the nerves and muscles, leading to involuntary movements and spasms. Alcoholism can cause hypomagnesemia by reducing the absorption and increasing the excretion of magnesium.
B. Positive Chvostek's sign
Positive Chvostek's sign is not a sign of hypomagnesemia, but of hypocalcemia, which is a low level of calcium in the blood. Calcium is another mineral that is important for the function of nerves and muscles. A low calcium level can cause tetany, which is a condition of sustained muscle contraction. Chvostek's sign is a test that involves tapping the facial nerve in front of the ear and observing for a twitching of the facial muscles. A positive Chvostek's sign indicates hypocalcemia, not hypomagnesemia.
C. Decreased deep tendon reflexes
Decreased deep tendon reflexes are not a sign of hypomagnesemia, but of hypermagnesemia, which is a high level of magnesium in the blood. A high magnesium level can cause hyporeflexia, which is a reduced or absent response to stimuli. Magnesium has a sedative effect on the nerves and muscles, and can inhibit the transmission of impulses. Hypermagnesemia can be caused by excessive intake or impaired excretion of magnesium.
D. Polyuria and flank pain
Polyuria and flank pain are not signs of hypomagnesemia, but of kidney problems, such as infection, stones, or failure. Polyuria is the production of abnormally large amounts of urine, and flank pain is the pain in the side or back below the ribs. These symptoms can indicate damage or inflammation of the kidneys, which can affect the balance of fluids and electrolytes in the body. Hypomagnesemia does not directly cause polyuria or flank pain, but it can be a result of kidney dysfunction.

The nurse is conducting dietary teaching for a client diagnosed with coronary artery disease. Which statement made by the client indicates an understanding of fat sources and the need to limit saturated fats?
A. "Meat and eggs mostly contain unsaturated fats."
This is not a correct statement. Meat and eggs mostly contain saturated fats, which are fats that have no double bonds between the carbon atoms. Saturated fats are solid at room temperature and can raise the level of low-density lipoprotein (LDL) cholesterol in the blood. LDL cholesterol is also known as the "bad" cholesterol because it can deposit on the walls of the arteries and cause atherosclerosis, which is the narrowing and hardening of the arteries. The client should limit the intake of saturated fats to less than 10% of the total calories per day.
B. "Coconut oil has a rich flavor and is a good cooking oil."
This is not a correct statement. Coconut oil is a saturated fat, which is a fat that has no double bonds between the carbon atoms. Coconut oil is solid at room temperature and can raise the level of low-density lipoprotein (LDL) cholesterol in the blood. LDL cholesterol is also known as the "bad" cholesterol because it can deposit on the walls of the arteries and cause atherosclerosis, which is the narrowing and hardening of the arteries. The client should avoid or limit the use of coconut oil and other sources of saturated fats.
C. "Olive oil is a monounsaturated fat and is recommended."
This is the correct statement. Olive oil is a monounsaturated fat, which is a fat that has one double bond between the carbon atoms. Monounsaturated fats are liquid at room temperature and can lower the level of low-density lipoprotein (LDL) cholesterol in the blood. LDL cholesterol is also known as the "bad" cholesterol because it can deposit on the walls of the arteries and cause atherosclerosis, which is the narrowing and hardening of the arteries. The client should use olive oil and other sources of monounsaturated fats instead of saturated fats.
D. "Butter is high in saturated fats so I should avoid it."
This is not a correct statement. Butter is high in saturated fats, which are fats that have no double bonds between the carbon atoms. Saturated fats are solid at room temperature and can raise the level of low-density lipoprotein (LDL) cholesterol in the blood. LDL cholesterol is also known as the "bad" cholesterol because it can deposit on the walls of the arteries and cause atherosclerosis, which is the narrowing and hardening of the arteries. The client should avoid or limit the intake of butter and other sources of saturated fats.

Which statement, made by the client with coronary artery disease, alerts the nurse that the client may be experiencing difficulty adapting to the illness?
A. "I feel a little anxious when I get chest discomfort."
This is not an alarming statement. Feeling a little anxious when experiencing chest discomfort is a normal and understandable reaction. Chest discomfort can be a sign of angina, which is a condition where the heart muscle does not get enough oxygen due to reduced blood flow. Angina can cause pain, pressure, or tightness in the chest, and can be triggered by physical or emotional stress. The client should try to relax and take their medication as prescribed to relieve the discomfort.
B. "I know that I should carry my medication with me in case I develop chest pain."
This is not an alarming statement. Knowing that they should carry their medication with them in case they develop chest pain is a sign of good self-care and awareness. The client should have a quick-relief medication, such as nitroglycerin, that can dilate the coronary arteries and improve the blood flow to the heart. The client should take the medication as soon as they feel chest pain and follow the instructions on how to use it.
C. "My wife and I will learn to cook using the 'good' cooking oils."
This is not an alarming statement. Learning to cook using the "good" cooking oils is a sign of positive lifestyle change and adaptation. The client should avoid or limit the intake of saturated and trans fats, which can raise the level of low-density lipoprotein (LDL) cholesterol in the blood. LDL cholesterol is also known as the "bad" cholesterol because it can deposit on the walls of the arteries and cause atherosclerosis, which is the narrowing and hardening of the arteries. The client should use unsaturated fats, such as olive oil, canola oil, or sunflower oil, which can lower the LDL cholesterol and increase the high-density lipoprotein (HDL) cholesterol. HDL cholesterol is also known as the "good" cholesterol because it can remove the excess cholesterol from the arteries and transport it to the liver.
D. "I usually wait about two hours after I feel chest discomfort to seek medical attention."
This is the alarming statement. Waiting about two hours after feeling chest discomfort to seek medical attention is a sign of denial and delay. Chest discomfort can be a symptom of a heart attack, which is a life-threatening emergency where the blood flow to the heart is blocked and the heart muscle begins to die. The client should seek immediate medical attention if they experience chest pain that lasts more than a few minutes, or if it is accompanied by other signs, such as shortness of breath, nausea, sweating, or arm or jaw pain. The sooner the client receives treatment, the better the chance of survival and recovery.
