The type of lipoprotein that carries cholesterol from tissues to the liver for excretion is:
- A. Very low-density lipoprotein
- B. Intermediate-density lipoprotein
- C. Low-density lipoprotein
- D. High-density lipoprotein
Correct Answer: D
Rationale: The correct answer is D, High-density lipoprotein (HDL). HDL is known as the 'good' cholesterol and plays a crucial role in transporting cholesterol from tissues back to the liver for excretion. This process helps in reducing the buildup of cholesterol in the bloodstream, thus lowering the risk of heart diseases. Very low-density lipoprotein (Option A), Intermediate-density lipoprotein (Option B), and Low-density lipoprotein (Option C) are not responsible for carrying cholesterol back to the liver for excretion like HDL does. Instead, they are associated with different functions related to cholesterol transportation within the body.

A client is admitted to the hospital with the diagnosis of a right-sided brain attack (CVA). The client is right-handed. Which task will be most difficult for this client?
- A. Eating meals
- B. Writing letters
- C. Combing the hair
- D. Dressing every morning
Correct Answer: B
Rationale: The correct answer is B: Writing letters. Writing requires fine motor skills, which are often impaired in a right-handed person with a right-sided CVA. Eating meals (choice A) involves gross motor skills and can be adapted for easier handling. Combing the hair (choice C) and dressing every morning (choice D) also require fine motor skills, but they are generally less complex and demanding than writing letters.
Which outcome should the nurse identify for the client diagnosed with fluid volume excess?
- A. The client will void a minimum of 30 mL per hour
- B. The client will have elastic skin turgor
- C. The client will have no adventitious breath sounds
- D. The client will have a serum creatinine of 1.4 mg/dL
Correct Answer: C
Rationale: The correct answer is C. Absence of adventitious breath sounds indicates that fluid is not accumulating in the lungs, a key outcome in managing fluid volume excess. Choices A, B, and D are incorrect. A client with fluid volume excess may not necessarily void a minimum of 30 mL per hour, have elastic skin turgor, or have a specific serum creatinine level. The absence of adventitious breath sounds is a more direct indicator of managing fluid volume excess.
Which of the following is a common side effect of the drug metformin?
- A. Weight loss
- B. Weight gain
- C. Drowsiness
- D. Hypertension
Correct Answer: A
Rationale: The correct answer is A, weight loss. Metformin is commonly associated with weight loss as a side effect rather than weight gain. Metformin works by decreasing glucose production in the liver and improving insulin sensitivity, which can lead to weight loss. Choices B, C, and D are incorrect because weight gain, drowsiness, and hypertension are not typically common side effects of metformin.
Listed below are five categories that identify the responsibilities of the practical nurse manager in personnel management. Which of these categories is most appropriate for the task 'Conduct physical training'?
- A. Accountability
- B. Personal/professional development
- C. Individual training
- D. Military appearance/physical condition
Correct Answer: D
Rationale: The correct answer is D: 'Military appearance/physical condition.' The task 'Conduct physical training' aligns with the category of 'Military appearance/physical condition,' as it involves overseeing physical training activities related to maintaining a certain physical standard. Choices A, B, and C are incorrect because 'Accountability' pertains to being answerable for one's actions, 'Personal/professional development' focuses on individual growth and learning, and 'Individual training' is specific to training on a personal level, none of which directly relate to the task of conducting physical training in the context of military appearance and physical condition.
