Correct Answer: B

Rationale: When cimetidine decreases the metabolism of imipramine, it leads to an increased concentration of imipramine in the body, which can result in imipramine toxicity. This increased risk of toxicity is the likely effect of this drug interaction. Choice A is incorrect because cimetidine's effect on imipramine metabolism does not impact the therapeutic effects of cimetidine. Choice C is incorrect because the interaction does not decrease the risk of adverse effects of cimetidine. Choice D is incorrect as the increased concentration of imipramine can lead to toxicity, not increased therapeutic effects.

Correct Answer: A

Rationale: The correct answer is walking briskly. Weight-bearing exercises, such as brisk walking, are recommended for individuals at risk for osteoporosis because they help maintain bone mass and prevent bone loss. Riding a bicycle and performing isometric exercises are not weight-bearing activities, and therefore, may not provide the same bone-strengthening benefits as walking. High-impact aerobics can increase the risk of fractures in individuals with osteoporosis due to the high level of impact involved.

Correct Answer: A

Rationale: Postural hypotension is a common sign of extracellular fluid volume deficit due to decreased blood volume, leading to a drop in blood pressure upon standing. Distended neck veins, dependent edema, and bradycardia are not typically associated with extracellular fluid volume deficit. Distended neck veins are more indicative of fluid volume overload, dependent edema is a sign of fluid retention, and bradycardia is not a common finding in extracellular fluid volume deficit.

Correct Answer: C

Rationale: The healthcare professional should question the dose indicated in the prescription. In this case, '0.25' is incomplete without a unit of measurement, such as mg (milligrams). Without a specified unit, the dose lacks the necessary information for accurate administration. Choices A, B, and D are not incorrect components to question in medication prescriptions; however, in this scenario, the incompleteness of the dose is the most critical concern that needs clarification to ensure safe and effective medication administration.

Correct Answer: A

Rationale: The correct answer is to repeat each joint motion five times during each session. Repetition is crucial to maintaining joint flexibility and muscle function. By ensuring each joint motion is repeated, the client can benefit fully from the passive range-of-motion exercises. Choice B is incorrect because quick performance may compromise technique and risk injury. Choice C is incorrect as neglecting less affected joints can lead to imbalances and hinder overall progress. Choice D is incorrect as assessing the client's range of motion beforehand is vital, but it is not the immediate action to take during the exercise session.
