Correct Answer: A

Rationale: The correct answer is A: Test the patient's hearing promptly. This is because before dispensing hearing aids, it is crucial to accurately assess the patient's hearing ability. Testing the patient's hearing promptly allows the healthcare professional to determine the type and degree of hearing loss, which is essential for selecting the appropriate hearing aids. Performing an otoscopy (choice B) may be part of the assessment but does not provide information on hearing ability. Measuring the width of the patient's ear canal (choice C) is not necessary for dispensing hearing aids. Referring the patient to his primary care physician (choice D) may delay the process of obtaining hearing aids and is not directly related to the responsibility of the health professional dispensing hearing aids.

Correct Answer: C

Rationale: The correct answer is C because anesthetics used during surgery can decrease bladder contractility, leading to urinary retention. By inserting an indwelling catheter, the nurse ensures proper drainage of urine and prevents bladder distention. This helps to maintain the patient's comfort and prevent complications such as urinary retention and potential bladder injury. Choice A is incorrect because inserting a catheter is not primarily to prevent uncontrollable voiding during surgery. Choice B is incorrect as local trauma does not promote excessive urine incontinence necessitating catheterization. Choice D is incorrect because the primary purpose of catheter insertion is not to prevent interruption of the procedure by bathroom breaks.

Correct Answer: D

Rationale: The correct answer is D. Having emergency equipment readily available is crucial during allergy skin testing as it can lead to severe allergic reactions. This precaution ensures prompt intervention in case of anaphylaxis. Other choices are incorrect because: A) Recent immunizations do not directly impact the skin testing process. B) Administering albuterol is not a standard pre-test requirement. C) Prophylactic epinephrine is not routinely given before allergy skin testing.

Correct Answer: B

Rationale: The correct answer is B: The specific hormones secreted by the tumor. Pituitary adenomas are known to secrete hormones that can lead to various endocrine disorders. Understanding the specific hormones secreted by the tumor is crucial in determining the clinical manifestations and planning appropriate treatment. Choices A, C, and D are incorrect because the primary determinant of the effects of the tumor in this case is the hormonal activity rather than whether the tumor uses aerobic or anaerobic respiration, the patient's pre-existing health status, or whether the tumor is primary or metastatic.

Correct Answer: B

Rationale: The correct answer is B: Uses humility. Critical thinking in nursing involves being open-minded, self-aware, and willing to consider different perspectives. Humility allows nurses to acknowledge their limitations, seek feedback, and continuously learn and improve. Instilling faith (A) may be important but does not directly relate to critical thinking standards. Self-confidence (C) can be beneficial, but excessive confidence can lead to closed-mindedness. Supportiveness (D) is valuable in patient care but does not specifically demonstrate critical thinking standards. In summary, humility enables nurses to approach patient communication with an open and reflective mindset, essential for applying critical thinking standards effectively.
