Correct Answer: A

Rationale: When monitoring rectal temperature, it is crucial to use a thermometer with a short, blunt insertion end to prevent injury and ensure accurate readings. Using a thermometer with a long, slender tip can pose a risk of perforation or discomfort for the client. Therefore, the appropriate action for the nurse to take is to obtain a thermometer with a short, blunt insertion end. Using the available thermometer as is would not address the safety concerns. Requesting a new thermometer is unnecessary when a suitable one is available by just obtaining it. Measuring the temperature orally instead would not provide the required rectal temperature monitoring.

Correct Answer: A

Rationale: Administering pain medication before changing the dressing is the priority action as it will help alleviate the client's pain and improve comfort. Choice B, changing the dressing less frequently, may hinder proper wound care and healing. Applying a topical anesthetic (choice C) might offer some relief but systemic pain medication is more effective. Using a non-adherent dressing (choice D) can reduce pain during dressing changes, but addressing immediate pain with medication is the most appropriate intervention in this case.

Correct Answer: C

Rationale: The nurse most likely observed plantar warts, which appear on the sole of the foot and are caused by the papillomavirus. Corns (Choice A) and calluses (Choice B) are areas of thickened skin caused by pressure or friction and are not typically associated with viruses. Athlete's foot (Choice D) is a fungal infection that usually affects the skin between the toes and is not caused by a virus like plantar warts.

Correct Answer: D

Rationale: The correct answer is D: Normal breath sounds. In the scenario described, the nurse hears normal bronchovesicular breath sounds, which are moderate in intensity and resemble blowing as air moves through the larger airways during inspiration and expiration. Crackles (choice A) are typically heard in conditions like heart failure or pneumonia and are not present in this case. Rhonchi (choice B) are low-pitched, continuous sounds often associated with conditions like chronic bronchitis or bronchiectasis. Friction rub (choice C) is a grating sound usually heard in conditions like pleurisy or pericarditis, which is not the case here where normal breath sounds are heard.

Correct Answer: A

Rationale: A positive Chvostek's sign is a clinical indication of low calcium levels, known as hypocalcemia. This sign is elicited by tapping the facial nerve anterior to the ear, resulting in facial muscle twitching. The correct laboratory finding associated with a positive Chvostek's sign is decreased calcium. Elevated potassium (Choice B) is not typically associated with Chvostek's sign but can be seen in conditions like renal failure. Increased sodium (Choice C) is not directly related to Chvostek's sign and is more commonly associated with hypernatremia. Low hemoglobin (Choice D) is not the expected laboratory finding in a client with a positive Chvostek's sign; instead, it suggests anemia, which is unrelated to this clinical manifestation.
