Correct Answer: D

Rationale: The correct answer is D because a client with a fractured femur and sudden chest pain may be experiencing a pulmonary embolism, which requires immediate assessment. Choice A is incorrect because although severe pain is present, it is more indicative of musculoskeletal issues related to urolithiasis rather than a life-threatening condition. Choice B, related to acute cholecystitis, is less urgent than choice D as the pain radiating to the right shoulder is a common symptom but does not indicate an immediate life-threatening situation. Choice C, regarding a client post-total knee arthroplasty with a pain level of 8, is important but not as urgent as a potential pulmonary embolism in choice D.

Correct Answer: B

Rationale: The correct answer is B: Decreased anginal pain. Verapamil is a calcium channel blocker used to relieve angina by reducing myocardial oxygen demand. Monitoring for decreased anginal pain is essential as it indicates a therapeutic response to the medication. Choices A, C, and D are incorrect as verapamil's primary goal in this context is not to decrease blood pressure, heart rate, or anxiety.

Correct Answer: A

Rationale: The correct answer is A. Instructing the client to remain still once the gel pads are attached is crucial to obtaining accurate ECG readings. Choice B is incorrect as electrodes are typically placed on the chest, not the breast. Choice C is incorrect because the client should lie flat during an ECG, not sit up. Choice D is incorrect because the client should breathe normally, rather than holding their breath, throughout the procedure.

Rationale: The correct answer is D. Rinsing the skin with soap and water following exposure to the botulism toxin is crucial as it helps remove the toxin from the skin, preventing further absorption. Choices A, B, and C are incorrect. Immunoglobulin E (IgE) is not used in the management of botulism. Airborne precautions are not necessary for botulism as it is not transmitted through the air. Aminoglycoside medications are not the treatment of choice for botulism.
