Question 3 of 5
An aging client diagnosed with schizophrenia spectrum disorder takes an antipsychotic and a beta-adrenergic blocking agent for hypertension. Understanding the combined side effects of these drugs, which statement by a nurse is most appropriate?
Correct Answer: C
Rationale: Step 1: Antipsychotics can cause orthostatic hypotension, making the client dizzy or lightheaded when standing up quickly. Step 2: Beta-blockers can also lower blood pressure, exacerbating orthostatic hypotension. Step 3: Rising slowly helps prevent a sudden drop in blood pressure, reducing the risk of falls and injuries. Step 4: Option C is the most appropriate because it directly addresses the potential side effect of orthostatic hypotension from the combination of antipsychotic and beta-blocker medications. Summary: Option A focuses on relaxation techniques, B on general health advice, and D on sun protection, which are not directly related to the combined side effects of the medications.
Question 4 of 5
Under which circumstance should a nurse administer a prn dose of benztropine?
Correct Answer: C
Rationale: The correct answer is C because benztropine is commonly used to treat extrapyramidal symptoms like tremors and shuffling gait caused by antipsychotic medications. Administering a prn dose in this circumstance helps alleviate these specific symptoms. Choice A is incorrect as benztropine is not indicated for managing aggression. Choice B is also incorrect as benztropine is not used for calming purposes before bedtime. Choice D is incorrect as benztropine is not indicated for constipation relief. Administering benztropine prn for tremors and shuffling gait aligns with its pharmacological action and therapeutic use.
Question 5 of 5
A patient with bipolar disorder was hospitalized 5 days ago and has received lithium 600 mg TID. The staff now observes agitation, pressured speech, poor personal hygiene, hyperactivity, and bizarre clothing. Select the nurse’s best action.
Correct Answer: A
Rationale: The correct answer is A. Measuring the serum lithium level is crucial to assess if the patient is within the therapeutic range. Symptoms of lithium toxicity, such as agitation and hyperactivity, suggest the need for monitoring. B is incorrect as the priority is assessing the medication effectiveness first. C and D are irrelevant to the immediate concern of potential lithium toxicity.
