A nurse is caring for a client who has chronic hypertension. The client's morning vital signs include BP 140/80 mm Hg, heart rate 54/min, and respiratory rate 18/min. Which of the following medications should the nurse plan to withhold?
Lisinopril
Hydrochlorothiazide D
Aspirin
Atenolol
The Correct Answer is D
D. Atenolol is a beta-blocker used to treat hypertension and lower heart rate. Given the client's low heart rate of 54 beats per minute (bradycardia), there is a potential concern about further lowering the heart rate with atenolol. Therefore, the nurse should consider withholding atenolol and consulting with the healthcare provider regarding the low heart rate before administering the medication.
A. Lisinopril is an angiotensin-converting enzyme (ACE) inhibitor used to treat hypertension. With a blood pressure of 140/80 mm Hg, it is within the normal range for a client with chronic hypertension.
B. Hydrochlorothiazide is a diuretic commonly used to treat hypertension. With a blood pressure of 140/80 mm Hg, it is within the normal range for a client with chronic hypertension. Therefore, there is no immediate need to withhold hydrochlorothiazide based on the current blood pressure reading.
C. Aspirin is commonly used for cardiovascular protection in clients with hypertension. It is not typically withheld based on blood pressure readings alone unless there are other contraindications or concerns.

Correct Answer is C
Explanation
C. Sublingual nitroglycerin is rapidly absorbed through the mucous membranes under the tongue, and its effects are usually felt within 1 to 5 minutes. Patients should experience relief from angina symptoms shortly after administration.
A. While sublingual nitroglycerin can be taken every 5 minutes for a maximum of three doses for acute angina attacks, it should not be taken every 10 minutes. Taking it too frequently can lead to excessive vasodilation and potentially harmful side effects.
B. Nitroglycerin primarily dilates blood vessels rather than affecting heart rate. While it may cause a transient decrease in blood pressure, it does not typically slow heart rate.
D. Sublingual nitroglycerin should be taken on an empty stomach for optimal absorption. Food can delay absorption and decrease the effectiveness of the medication.
Correct Answer is C
Explanation
A. Opioid overdose typically results in central nervous system depression, which can lead to bradycardia (slow heart rate) rather than tachycardia. Bradycardia occurs due to decreased sympathetic nervous system activity.
B. Bradyppnea is a common finding in opioid overdose due to the depressive effect of opioids on the respiratory center in the brainstem. Opioids can suppress the drive to breathe, leading to shallow and rapid breathing, or even respiratory arrest in severe cases.
C. Sedation or drowsiness is a hallmark feature of opioid overdose. Oxycodone, like other opioids, acts on the central nervous system to produce analgesia and sedation. In cases of overdose, sedation may progress to unconsciousness and respiratory depression, which can be life-threatening.
D. Opioid overdose typically causes pinpoint (constricted) pupils rather than dilated pupils. The constriction of pupils, known as miosis, is a classic sign of opioid toxicity due to the suppression of the sympathetic nervous system.
