Which of the following dietary interventions prevents the precipitation of calcium renal stones?
- A. High fiber diet
- B. Increased protein intake
- C. High fluid intake
- D. Intake of zinc
Correct Answer: C
Rationale: The correct answer is C: High fluid intake. Adequate hydration helps prevent calcium from becoming concentrated in the urine, reducing the risk of calcium stone formation. Increased fiber intake (choice A) may help prevent other types of stones but not specifically calcium stones. Increased protein intake (choice B) can actually increase calcium excretion, potentially increasing the risk of calcium stone formation. Zinc intake (choice D) does not directly impact calcium stone formation. In summary, high fluid intake is crucial for preventing the precipitation of calcium renal stones due to its role in diluting urine and preventing calcium concentration.

During the physical examination of a client for a possible neurologic disorder, how can the nurse examine the client for stiffness and rigidity of the neck?
- A. By positioning the client flat on bed for at least 3 hrs
- B. By moving the head and chin of the client toward the chest
- C. By asking the client to bend and pick up small and large objects on the floor
- D. By introducing a painful stimulus on the neck
Correct Answer: B
Rationale: The correct answer is B. To examine stiffness and rigidity of the neck, the nurse should move the client's head and chin toward the chest. This maneuver assesses for resistance and limitation in neck flexion, which can indicate stiffness and rigidity commonly seen in neurologic disorders like meningitis or cervical dystonia.
A: Positioning the client flat on the bed for hours does not specifically target neck stiffness and rigidity.
C: Asking the client to bend and pick up objects assesses motor function, not neck stiffness.
D: Introducing a painful stimulus is not a standard or appropriate method for examining neck stiffness and rigidity.
Postural Hypotension is A drop in systolic pressure less than 10 mmHg when patient changes position from lying to sitting.
- A. A drop in systolic pressure greater than 10 mmHg when patient changes position from lying to sitting
- B. A drop in diastolic pressure less than 10 mmHg when patient changes position from lying to sitting
- C. A drop in diastolic pressure greater than 10 mmHg when patient changes position from lying to sitting
Correct Answer: A
Rationale: The correct answer is A because postural hypotension is defined as a drop in systolic blood pressure of greater than 20 mmHg or a drop in diastolic blood pressure of greater than 10 mmHg within 3 minutes of standing from a sitting or supine position. Therefore, a drop in systolic pressure greater than 10 mmHg when changing from lying to sitting is indicative of postural hypotension.
Choice B is incorrect as postural hypotension is primarily defined by changes in systolic blood pressure, not diastolic. Choice C is incorrect because a drop in diastolic pressure greater than 10 mmHg is not the defining characteristic of postural hypotension. Choice D is not provided.
Aling Loida, who was admitted for acute pancreatitis, starts complaining of acute abdominal pain, which of the following would be an appropriate nursing interventions by Nurse Norma?
- A. administer morphine sulfate as ordered
- B. obtain daily weights
- C. maintain Aling Loida on high calorie, high protein diet
- D. place her on supine position
Correct Answer: A
Rationale: The correct answer is A: administer morphine sulfate as ordered. This is the appropriate nursing intervention because acute abdominal pain is a common symptom of acute pancreatitis, and morphine sulfate is a commonly used medication to relieve severe abdominal pain. Administering morphine sulfate will help alleviate Aling Loida's discomfort and improve her overall well-being.
Choice B is incorrect because obtaining daily weights is not directly related to managing acute abdominal pain in this scenario. Choice C is incorrect as maintaining Aling Loida on a high calorie, high protein diet may exacerbate her symptoms due to the acute pancreatitis. Choice D is incorrect as placing her on a supine position may not address the underlying cause of the abdominal pain and could potentially worsen her condition.
60 year-old Mrs. Torres arrived just in time for her doctor’s appointment. She complains of pain and stiffness in her back. She is suspected of having osteoporosis. Nurse Ariane will inform Mrs. Torres that the primary complication of osteoporosis is:
- A. Increased trabeculae
- B. poor posture
- C. chronic pain
- D. fractures
Correct Answer: D
Rationale: The correct answer is D: fractures. Osteoporosis weakens bones, making them more prone to fractures. Fractures are the primary complication of osteoporosis due to decreased bone density. Increased trabeculae (A) is incorrect as osteoporosis leads to decreased bone density, not increased. Poor posture (B) may be a result of osteoporosis but is not its primary complication. Chronic pain (C) can occur with osteoporosis but is not as directly linked as fractures.
A client is receiving methotrexate (Mexate), 12g/m2 IV to treat osteogenic carcinoma. During methotrexate therapy, the nurse expects the client to receive which other drug to protect normal cells?
- A. Probenecid (Benemid)
- B. Cytarabine (ara-C, cystosine arabinoside [Cytosar-U])
- C. Thioguanine (6-thioguanine, 6-TG)
- D. Leucovorin (Citrovorum factor or folinic acid [wellcovirin])
Correct Answer: D
Rationale: The correct answer is D, Leucovorin. Leucovorin is administered with methotrexate to protect normal cells from methotrexate toxicity by acting as a "rescue" agent. Methotrexate inhibits dihydrofolate reductase, leading to decreased levels of tetrahydrofolate needed for DNA synthesis. Leucovorin bypasses this step by directly providing the reduced form of folic acid, thus preventing toxicity in normal cells. Probenecid (choice A) is not used to protect normal cells during methotrexate therapy. Cytarabine (choice B) and Thioguanine (choice C) are not rescue agents for methotrexate toxicity.
