A nurse is preparing to administer metoprolol 25 mg PO to a client with a history of hypertension and heart failure. The client’s vital signs are: BP 132/78 mm Hg, HR 86 beats per minute, and respiratory rate 18 breaths per minute. Which action should the nurse take?
Give half of the prescribed dose
Give the full dose as ordered
Delay the dose until the pulse is below 60
Omit the dose and record the pulse rate as the reason
The Correct Answer is B
Choice A reason: Giving half the dose of metoprolol is inappropriate without a medical order, as it may reduce therapeutic efficacy. The client’s vital signs (BP 132/78, HR 86) are stable, indicating no need to alter the prescribed dose, which is intended to manage hypertension and heart failure.
Choice B reason: Metoprolol, a beta-blocker, reduces heart rate and blood pressure in hypertension and heart failure. The client’s vital signs (BP 132/78, HR 86) are within acceptable ranges, indicating the full 25 mg dose is safe and appropriate to maintain therapeutic control of their condition.
Choice C reason: Delaying the dose until the pulse is below 60 is unnecessary, as the client’s heart rate of 86 is not bradycardic. Metoprolol is indicated for heart rates above 60 in heart failure and hypertension, and withholding it could worsen blood pressure control.
Choice D reason: Omitting the dose due to a pulse of 86 is inappropriate, as this heart rate is not dangerously low. Metoprolol is prescribed to manage hypertension and heart failure, and withholding it without clinical justification could lead to uncontrolled symptoms or disease progression.

Correct Answer is B
Explanation
Choice A reason: An untidy house and yard may indicate poor organization or neglect but is not specific to hoarding. It could result from various factors, such as depression or physical limitations, and does not inherently pose a dangerous safety risk associated with hoarding behaviors.
Choice B reason: A single path through the yard and house indicates severe accumulation of items, characteristic of hoarding disorder. This creates significant safety hazards, such as fire risks, tripping hazards, or blocked exits, which can impede emergency access and pose immediate dangers to the client’s well-being.
Choice C reason: Neighbor complaints about cats may suggest pet hoarding, a subtype of hoarding disorder. However, without evidence of excessive clutter or unsafe living conditions, this alone is less indicative of dangerous hoarding compared to physical obstructions like a single path through the home.
Choice D reason: A collection of scattered magazines may suggest early hoarding tendencies but does not necessarily indicate a dangerous level of hoarding. It lacks the severity of safety risks, such as blocked pathways or fire hazards, associated with a single path through the home.
Correct Answer is A
Explanation
Choice A reason: SSRIs increase serotonin levels in the brain, effectively managing GAD with a low risk of dependence. Side effects like nausea or headache are generally mild and transient, making SSRIs safer compared to other classes, as they do not cause significant physiological dependence or severe adverse effects.
Choice B reason: Tricyclic antidepressants affect multiple neurotransmitters, effectively treating GAD but with significant side effects like anticholinergic effects (dry mouth, constipation) and potential cardiotoxicity. They carry a higher risk of overdose and side effects compared to SSRIs, making them less safe for long-term use in GAD.
Choice C reason: Benzodiazepines enhance GABA activity, providing rapid anxiety relief but with a high risk of physiological dependence and withdrawal. Side effects like sedation and cognitive impairment, along with abuse potential, make them less safe than SSRIs for long-term GAD management.
Choice D reason: MAOIs inhibit monoamine oxidase, increasing neurotransmitter levels for GAD treatment. However, they have significant side effects, including hypertensive crises from dietary tyramine, and require strict dietary restrictions. Their risk profile and potential for severe interactions make them less safe than SSRIs.
