1. Why is glucose an important molecule in a cell?
- A. Extraction of energy
- B. Synthesis of protein
- C. Building of genetic material
- D. Formation of cell membranes
Correct answer: A
Rationale: Glucose is a crucial molecule in cells because it serves as the primary source of energy through cellular respiration. Choice B, the synthesis of protein, is incorrect because proteins are typically synthesized from amino acids, not glucose. Choice C, the building of genetic material, is incorrect because genetic material, such as DNA and RNA, is not directly built from glucose. Choice D, the formation of cell membranes, is also incorrect as cell membranes are primarily composed of lipids and proteins, not glucose.
2. A client is admitted with deep vein thrombosis (DVT) and is receiving heparin therapy. What is the most important laboratory value to monitor during heparin therapy?
- A. Prothrombin time (PT)
- B. International normalized ratio (INR)
- C. Activated partial thromboplastin time (aPTT)
- D. Platelet count
Correct answer: C
Rationale: The activated partial thromboplastin time (aPTT) is the most important laboratory value to monitor during heparin therapy. It measures the intrinsic pathway of coagulation and is used to assess the effectiveness of heparin as an anticoagulant. Keeping the aPTT within the therapeutic range is crucial to prevent complications such as bleeding or clot formation. Prothrombin time (PT) and International normalized ratio (INR) are used to monitor warfarin therapy, not heparin. Platelet count is important to assess for thrombocytopenia, a potential side effect of heparin, but it is not the primary laboratory value to monitor the effectiveness of heparin therapy.
3. A male client with hypertension, who received new antihypertensive prescriptions at his last visit returns to the clinic two weeks later to evaluate his blood pressure (BP). His BP is 158/106, and he admits that he has not been taking the prescribed medication because the drugs make him feel bad. In explaining the need for hypertension control, the nurse should stress that an elevated BP places the client at risk for which pathophysiological condition?
- A. Stroke secondary to hemorrhage
- B. Myocardial infarction
- C. Heart failure
- D. Renal failure
Correct answer: A
Rationale: Stroke is a major complication of uncontrolled hypertension. Elevated BP, especially at levels like 158/106, can cause damage to blood vessels in the brain, leading to a hemorrhagic stroke. Controlling BP is essential to prevent such life-threatening events. Myocardial infarction (choice B) is more commonly associated with coronary artery disease, while heart failure (choice C) and renal failure (choice D) can be complications of uncontrolled hypertension but are not directly related to the elevated BP leading to a hemorrhagic stroke.
4. The nurse observes an unlicensed assistive personnel (UAP) using an alcohol-based gel hand cleaner before performing catheter care. The UAP rubs both hands thoroughly for 2 minutes while standing at the bedside. What action should the nurse take?
- A. Encourage the UAP to remain in the client's room until the hand rub is completed.
- B. Explain that the hand rub can be completed in less than 2 minutes.
- C. Inform the UAP that handwashing helps to promote better asepsis.
- D. Determine why the UAP was not wearing gloves in the client's room.
Correct answer: B
Rationale: The correct answer is B. Alcohol-based hand rubs are effective with a shorter rub time, typically around 20-30 seconds. Standing at the bedside for 2 minutes to rub hands thoroughly is unnecessary and can lead to wastage of resources. It's essential for the nurse to educate the UAP on proper hand hygiene techniques to ensure efficient and effective infection control practices. Choices A, C, and D are incorrect because encouraging the UAP to remain in the client's room, discussing handwashing instead of hand rubs, and questioning glove use are not the most appropriate actions in this scenario.
5. The nurse is caring for a client with syndrome of inappropriate antidiuretic hormone (SIADH). Which of the following interventions should the nurse implement?
- A. Encourage increased fluid intake
- B. Administer vasopressin
- C. Monitor for signs of dehydration
- D. Restrict oral fluids
Correct answer: D
Rationale: The correct intervention for a client with syndrome of inappropriate antidiuretic hormone (SIADH) is to restrict oral fluids. SIADH leads to excessive release of antidiuretic hormone (ADH), causing the body to retain water and diluting the sodium levels in the blood (hyponatremia). Restricting oral fluids helps prevent further water retention and worsening hyponatremia. Encouraging increased fluid intake (choice A) would exacerbate the problem by further diluting sodium levels. Administering vasopressin (choice B) is not indicated in SIADH, as the condition is characterized by excess ADH secretion. Monitoring for signs of dehydration (choice C) is not the priority in SIADH since the issue is water retention rather than dehydration.
