A nurse is collecting data from a client prior to administering atenolol.
For which of the following findings should the nurse withhold the medication?
A. Heart rate 50/min.
Atenolol is a beta-blocker that can significantly lower heart rate. A heart rate of 50/min is considered bradycardia (slow heart rate), and administering atenolol could further decrease the heart rate to a dangerously low level. Therefore, the nurse should withhold the medication in this case.
B. Respiratory rate 18/min.
A respiratory rate of 18/min is within the normal range (12-20 breaths per minute) and does not contraindicate the use of atenolol. Therefore, this finding would not require withholding the medication.
C. Oxygen saturation 95%.
An oxygen saturation of 95% is within the normal range (typically 95-100%) and does not contraindicate the use of atenolol. Thus, this finding would not necessitate withholding the medication.
D. Blood pressure 160/94 mm Hg.
While a blood pressure of 160/94 mm Hg indicates hypertension, atenolol is often prescribed to manage high blood pressure. Therefore, this finding would not require withholding the medication.

Full Explanation
The correct answer is choice A. Heart rate 50/min.
Choice A rationale:
Atenolol is a beta-blocker that can significantly lower heart rate. A heart rate of 50/min is considered bradycardia (slow heart rate), and administering atenolol could further decrease the heart rate to a dangerously low level. Therefore, the nurse should withhold the medication in this case.
Choice B rationale:
A respiratory rate of 18/min is within the normal range (12-20 breaths per minute) and does not contraindicate the use of atenolol. Therefore, this finding would not require withholding the medication.
Choice C rationale:
An oxygen saturation of 95% is within the normal range (typically 95-100%) and does not contraindicate the use of atenolol. Thus, this finding would not necessitate withholding the medication.
Choice D rationale:
While a blood pressure of 160/94 mm Hg indicates hypertension, atenolol is often prescribed to manage high blood pressure. Therefore, this finding would not require withholding the medication.

A nurse is caring for a client who is postoperative and has developed atelectasis.
Which of the following findings should the nurse expect?
A. Facial flushing.
Facial flushing. Facial flushing is not typically associated with atelectasis. Atelectasis is the collapse of a portion of the lung, which can lead to decreased oxygenation and respiratory distress but does not directly cause facial flushing. Flushing may be related to other factors such as fever or allergic reactions.
B. Dry cough.
Dry cough. A dry cough can be a common symptom of atelectasis. As the lung tissue collapses and airways become obstructed, it can lead to irritation and a dry, non-productive cough as the body attempts to clear the airway. So, a dry cough is an expected finding in a client with atelectasis.
C. Decreasing respiratory rate.
Decreasing respiratory rate. A decreasing respiratory rate is not typically associated with atelectasis. In fact, atelectasis often leads to an increased respiratory rate as the body tries to compensate for the reduced oxygen exchange. The patient may experience tachypnea (rapid breathing) as a result.
D. Increasing dyspnea.
Increasing dyspnea. Increasing dyspnea is a common and expected finding in a client with atelectasis. As lung tissue collapses and oxygen exchange is compromised, the patient will likely experience worsening shortness of breath. This is a concerning symptom and should be closely monitored, as it may indicate a need for intervention to improve lung expansion and oxygenation.

A nurse administered nitroglycerin sublingually to a client who has angina pectoris and experienced chest pain.
The client states that his chest pain is relieved but now he has a headache.
Which of the following responses by the nurse is appropriate?
A. "A headache indicates tolerance to the medication.”.
Tolerance to nitroglycerin is not indicated by the presence of a headache. Nitroglycerin is a vasodilator used to relieve angina, and headaches can be a common side effect.
B. "It sounds as if you are allergic to this medication.”.
Allergic reactions to nitroglycerin are rare, and a headache is not a typical symptom of an allergy to this medication.
C. "A headache is a common adverse effect of this medication, but it will probably occur less often over time.”.
"A headache is a common adverse effect of this medication, but it will probably occur less often over time.”. This is the correct response. Nitroglycerin commonly causes headaches due to its vasodilatory effects. Patients often experience this side effect initially, but it tends to improve or occur less frequently with continued use. The nurse should educate the client about this and reassure them that the headaches should diminish over time.
D. "Your headache is probably a result of anxiety about the chest pain.”.
Anxiety may exacerbate chest pain, but it is not the likely cause of the headache. It is important to address the headache as a potential side effect of the medication.

A nurse is collecting data from a client who has hypokalemia as a result of nausea, vomiting, and diarrhea.
Which of the following findings should the nurse expect?
A. Extreme thirst.
Extreme thirst is not a typical finding in a client with hypokalemia. Hypokalemia is an electrolyte imbalance that can lead to symptoms like weakness and irregular heartbeats, but extreme thirst is not a direct result of low potassium levels.
B. Weak, irregular pulse.
"Weak, irregular pulse" is the correct response. Hypokalemia can lead to cardiac arrhythmias, which may manifest as a weak, irregular pulse. Potassium plays a crucial role in maintaining the electrical activity of the heart, and low levels can disrupt normal heart rhythms.
C. Hyperactive bowel sounds.
Hyperactive bowel sounds are not typically associated with hypokalemia. Instead, you might expect diminished or absent bowel sounds in severe cases due to muscle weakness.
D. Hyperactive reflexes.
Hyperactive reflexes are not typically associated with hypokalemia. Instead, hypokalemia can lead to muscle weakness and potentially even paralysis in severe cases.
