1. Which brain structure serves as the heat-regulating center?

Correct answer: A: Hypothalamus

Rationale: The correct answer is the Hypothalamus. The hypothalamus is responsible for regulating body temperature, ensuring it stays within a narrow range. Moreover, the hypothalamus controls various essential bodily functions, such as hunger, thirst, and circadian rhythms. Choices B, C, and D are incorrect because the Pituitary Gland primarily produces and releases hormones, the Pons is involved in functions like sleep, respiration, and bladder control, and the Medulla Oblongata controls vital functions like breathing and heart rate, but not body temperature regulation.

2. The abbreviation pc is defined as ________________.

Correct answer: after the meal

Rationale: The correct answer is C: 'after the meal.' In medical terminology, 'pc' is an abbreviation for 'post cibum,' which means 'after eating' or 'after the meal.' This term is used to indicate when a medication should be taken concerning meals. Choices A, B, and D are incorrect. 'Before the meal' (A) is typically abbreviated as 'ac,' 'with the meal' (B) is abbreviated as 'pc,' and 'post corpi' (D) is not a valid medical abbreviation or term.

3. The family of a patient who is receiving therapeutic hypothermia states they do not understand why the patient is being kept so cold. What objective information can you provide to help address their concerns?

Correct answer: Provide research-based information about therapeutic hypothermia

Rationale: Providing research-based information about the benefits of therapeutic hypothermia for their loved one will provide evidence that this is an established therapy with generally positive outcomes. Families are certainly not expected to be familiar with critical care interventions, and their concerns should be addressed with evidence-based data whenever possible. Option A is not appropriate as sharing patient information violates privacy laws and does not address the family's concerns directly. Option C may not directly provide the detailed information the family needs to understand therapeutic hypothermia. Option D involves unnecessary escalation by immediately involving the physician, when providing education and information should be the initial step in addressing the family's concerns.

4. The nurse is reviewing the lab results of a patient taking lithium for schizoaffective disorder. The lab results show that the blood lithium value is 1.7 mcg/L. What would the nurse take as the priority action?

Correct answer: Hold the next dose of Lithium

Rationale: The correct answer is to hold the next dose of Lithium. The blood lithium value of 1.7 mcg/L exceeds the therapeutic range of 0.5-1.5 mcg/L, indicating potential toxicity. Holding the next dose is crucial to prevent further accumulation of lithium in the bloodstream. Inducing vomiting is not appropriate in this situation as the priority is to prevent further absorption of lithium. Administering an antiemetic is not the priority in lithium toxicity. Giving the next dose of lithium would exacerbate the toxicity and should be avoided.

5. When orally administering alendronate (Fosamax), a bisphosphonate drug, to a largely bed-bound patient being treated for osteoporosis, what is the most important nursing consideration?

Correct answer: Sit the head of the bed up for 30 minutes after administration

Rationale: The correct nursing consideration when administering bisphosphonates like alendronate is to sit the head of the bed up for 30 minutes after administration. Bisphosphonates are known to cause esophageal irritation, which can lead to esophagitis. By sitting upright, the patient reduces the time the medication spends in the esophagus, decreasing the risk of irritation and potential adverse effects. Giving the patient water to drink or feeding them immediately after administration can increase the risk of esophageal irritation. Assessing the patient for back pain or abdominal pain is important but not the most critical consideration during drug administration.
