Correct Answer: C

Rationale: A systolic blood pressure of 145 mm Hg falls within the range of 140-159 mm Hg, which is classified as Stage I hypertension. Normotensive individuals have a systolic blood pressure less than 120 mm Hg, making choice A incorrect. Prehypertension is characterized by a systolic blood pressure ranging from 120-139 mm Hg, excluding choice B. Stage II hypertension is diagnosed when the systolic blood pressure is greater than 160 mm Hg, making choice D incorrect. Therefore, the correct classification for a systolic blood pressure of 145 mm Hg is Stage I hypertension.

Correct Answer: C

Rationale: Clinical manifestations of asthma include increased use of accessory muscles, increased expiratory time, increased peak expiratory flow, and decreased oxygen saturation. Choice A, 'Decreased expiratory time,' is incorrect because asthma typically presents with increased expiratory time due to airway obstruction. Choice B, 'Increased peak expiratory flow,' is incorrect as asthma commonly leads to decreased peak expiratory flow due to airway constriction. Choice D, 'Increased oxygen saturation,' is incorrect because asthma exacerbations often result in decreased oxygen saturation levels.

Correct Answer: A

Rationale: The correct answer is that levothyroxine (Synthroid) should be taken in the morning. Taking it in the morning can help prevent interference with the client's sleeping pattern, as one of the side effects of levothyroxine is insomnia. Choice B is incorrect because levothyroxine is actually used to treat hypothyroidism and can help increase energy levels. Choice C is incorrect as there is no specific requirement for levothyroxine to be stored in a dark container. Choice D is incorrect because levothyroxine is more likely to increase heart rate rather than decrease it.

Correct Answer: C

Rationale: For a child scheduled for an appendectomy, the administration of a Fleet enema is not typically required. An IV line is often initiated for fluid and medication administration, maintaining NPO status is necessary to prevent aspiration during surgery, and administering intravenous antibiotics may be part of the preoperative regimen. Therefore, the correct choice that does not apply in this case is administering a Fleet enema.

Correct Answer: C

Rationale: In the scenario presented, the priority nursing goal for a client with renal calculi experiencing moderate to severe flank pain and nausea should be to manage pain. Pain management is crucial as it alleviates suffering, improves comfort, and enhances the quality of life for the client. In the case of ureteral colic from renal calculi, the cornerstone of management is effective pain control. Prompt analgesia, typically achieved with parenteral narcotics or nonsteroidal anti-inflammatory drugs (NSAIDs), is essential to provide relief and facilitate the passage of the calculi. While maintaining fluid and electrolyte balance is important in clients with renal calculi, addressing pain takes precedence as it directly impacts the client's immediate well-being. Controlling nausea and preventing urinary tract infections are also important aspects of care, but they are secondary to managing the primary concern of pain in this urgent situation.
