Correct Answer: B

Rationale: Amlodipine, a calcium channel blocker, can lead to peripheral edema as an adverse effect. The nurse should assess the client for swelling in the lower extremities, a common manifestation of this side effect. Monitoring for peripheral edema is crucial to ensure early detection and appropriate management.

Correct Answer: A

Rationale: To calculate the volume to administer, divide the desired dose by the available concentration. In this case, (80 mg / 10 mg/mL) = 8 mL.

Correct Answer: B

Rationale: Urinary retention is a common anticholinergic effect associated with amitriptyline, a tricyclic antidepressant. Amitriptyline can cause relaxation of the bladder sphincter muscles, leading to urinary retention. Monitoring for this adverse effect is crucial to prevent complications and ensure prompt intervention if needed.

Correct Answer: B

Rationale: Nifedipine, a calcium channel blocker, can lead to peripheral edema as an adverse effect. The nurse should monitor the client for swelling in the lower extremities, as it indicates the onset of edema. Hypertension is typically treated with Nifedipine and is not an adverse effect of the medication. Hyperglycemia and bradycardia are not commonly associated with Nifedipine use.

Correct Answer: C

Rationale: It is crucial to withhold all opioids, including Morphine, if the client's respiratory rate is 12/min or less, and promptly inform the healthcare provider. Respiratory depression is a significant adverse effect of opioids, and administering them when the respiratory rate is already compromised can further suppress breathing, leading to potentially life-threatening complications.
