Correct Answer: A

Rationale: Observing the rate, depth, and character of the client's respirations is crucial after repositioning a client experiencing shortness of breath. This action provides immediate information about the client's respiratory status. Checking blood pressure (Choice B) is not the priority in this situation, as assessing respirations is more urgent. Assessing the pulse (Choice C) is also important but does not provide direct information about the client's respiratory status. Offering supplemental oxygen (Choice D) may be necessary based on the assessment of respirations, but it should not be the first action taken without assessing the client's breathing pattern.

Correct Answer: A

Rationale: Urticaria, also known as hives, is a common manifestation of a mild allergic reaction. It presents as raised, red, itchy welts on the skin. Ptosis is drooping of the upper eyelid and is not typically associated with allergic reactions. Nausea is a gastrointestinal symptom that can occur with various conditions but is not specific to allergic reactions. Hematuria, which is the presence of blood in the urine, is not a typical manifestation of an allergic reaction.

Correct Answer: B

Rationale: The correct action when assessing an immobile patient for deep vein thromboses (DVTs) is to measure the calf circumference of both legs. This helps in detecting swelling or changes that may indicate the presence of a DVT. Removing elastic stockings every 4 hours (Choice A) is not necessary and can disrupt circulation. Lightly rubbing the lower leg for redness and tenderness (Choice C) can potentially dislodge a clot if present. Dorsiflexing the foot while assessing for patient discomfort (Choice D) is not a specific assessment for DVT and may not provide relevant information in this context.

Correct Answer: D

Rationale: The correct answer is to stand close to the cabinet when lifting it. This action keeps the object close to the nurse's center of gravity, reducing the risk of back strain. Bending at the waist (Choice A) can increase the risk of back injury as it puts strain on the lower back. Keeping feet close together (Choice B) does not provide a stable base of support for lifting a heavy object. Using back muscles for lifting (Choice C) is incorrect as it can lead to back strain and injury. Therefore, standing close to the cabinet when lifting it is the safest and most effective approach to prevent self-injury.

Correct Answer: A

Rationale: The nurse's priority in this situation is to determine the reason why the client is refusing to use the incentive spirometer. By understanding the client's concerns or barriers, the nurse can address them effectively and encourage the client to use the spirometer for optimal postoperative recovery. Insisting that the client use the spirometer without understanding the underlying reason may lead to further resistance. Administering pain medication as a solution does not address the root cause of refusal and may not be necessary if pain is not the primary reason for refusal. Documenting the refusal is important but should come after understanding the client's perspective to provide appropriate care and follow-up.
