Correct Answer: B

Rationale: The correct instruction for the client is to slowly rise from a sitting or lying down position. Isosorbide dinitrate, a nitrate, and hydrochlorothiazide, a diuretic, can both cause hypotension. When used together, their additive effects can further lower blood pressure, leading to orthostatic hypotension. Instructing the client to change positions slowly helps prevent a sudden drop in blood pressure, reducing the risk of dizziness or falls.

Correct Answer: A

Rationale: The correct answer is A: Drowsiness. Fluvoxamine is known to cause drowsiness as a potential side effect. Patients should be advised to avoid activities like driving that require alertness until they understand how the medication affects them. Dry mouth, insomnia, and headache are potential side effects of other medications used for anxiety disorders but are not typically associated with fluvoxamine.

Correct Answer: A

Rationale: The correct answer is A: QT prolongation. Ziprasidone is known to cause QT prolongation, which can potentially lead to serious cardiac issues. Monitoring the client's ECG is crucial to detect any changes and prevent adverse effects related to QT interval prolongation.

Correct Answer: C

Rationale: The correct answer is C. Glucocorticoids can cause skin thinning, which increases the likelihood of bruising. Thinning of the skin due to glucocorticoid therapy makes it more fragile and prone to injury, such as bruising, even with minimal trauma.

Correct Answer: C

Rationale: Reviewing the most recent coagulation lab values is crucial after receiving multiple doses of a new oral anticoagulant to ensure the patient is within the desired therapeutic range and to prevent adverse events related to over or under-anticoagulation. Notifying the healthcare provider of any concerning findings is important, but it may not be the immediate priority after receiving the third dose. Providing a PRN NSAID for gum discomfort is not typically indicated with oral anticoagulant therapy, as it may increase the risk of bleeding. Completing a medication variance report is more relevant in cases of medication errors or discrepancies, which may not apply in this scenario.
