Why does the nurse instruct the client to avoid Valsalva maneuvers?
- A. Clients BP will decrease momentarily
- B. Client may lose consciousness
- C. Client may suffer from a myocardial
- D. Clients BP will increase momentarily infarction
Correct Answer: B
Rationale: The correct answer is B because performing Valsalva maneuver can lead to a sudden drop in blood pressure, causing the client to lose consciousness. This occurs due to the increased intra-abdominal pressure leading to decreased venous return to the heart. Choices A, C, and D are incorrect as they do not accurately reflect the consequences of Valsalva maneuver. Option A stating that the client's blood pressure will decrease momentarily is incorrect as it actually increases initially. Option C suggesting that the client may suffer from a myocardial infarction is incorrect as Valsalva maneuver does not directly cause heart attacks. Option D implying that the client's blood pressure will increase momentarily is also incorrect as the immediate effect is a rise followed by a significant drop.

Nurse Melanie is teaching an adult class about the different types of hepatitis. Which statement does not pertain to hepatitis A?
- A. “Is caused by an RNA virus of the enterovirus family.”
- B. “It spreads primarily by fecal-oral route, usually through the ingestion of infcetd food or liquids.”
- C. “It may not be spread from sexual contact.”
- D. “Type A hepatitis occurs worldwide, especially in areas with overcrowding and poor sanitation.”
Correct Answer: A
Rationale: The correct answer is A because hepatitis A is caused by a virus from the Picornaviridae family, not the enterovirus family. Hepatitis A spreads through contaminated food or water, not through sexual contact. It is true that hepatitis A occurs worldwide in areas with poor sanitation, but the virus is not from the enterovirus family. Choices B, C, and D are incorrect because they all pertain to hepatitis A characteristics.
One of the complications of prolonged bed rest is decubitus ulcer. Which of the following can best prevent its occurrence?
- A. Massage reddened areas with lotion or oils
- B. Use special water mattress
- C. Turn frequently every 2 hours
- D. Keep skin clean and dry
Correct Answer: C
Rationale: The correct answer is C: Turn frequently every 2 hours. This helps redistribute pressure, preventing constant pressure on one area and reducing the risk of developing pressure ulcers. Turning every 2 hours promotes circulation and relieves pressure points.
A: Massaging reddened areas can worsen the condition by increasing friction and pressure.
B: While a special water mattress can help in preventing pressure ulcers, turning frequently is more effective.
D: Keeping the skin clean and dry is important for overall skin health but may not directly prevent pressure ulcers.
The most likely cause of her chief complaint this morning is
- A. A decrease in postoperative stress causing poiyuria
- B. The onset of diabetes mellitus, an unusual complication
- C. An expected result of the removal of the pituitary gland
- D. A frequent complication of the hypophysectomy
Correct Answer: D
Rationale: The correct answer is D because polyuria is a common complication following hypophysectomy (removal of the pituitary gland). This procedure can disrupt the regulation of antidiuretic hormone (ADH), leading to excessive urination. Choice A is incorrect as decreased stress would not cause polyuria. Choice B is unlikely as the onset of diabetes mellitus is not a typical immediate postoperative complication. Choice C is incorrect as removal of the pituitary gland would disrupt hormone regulation, possibly leading to polyuria, rather than being an expected result.
After reviewing the database, the nurse discovers that the patient’s vital signs have not been recorded by the nursing assistive personnel (NAP). Which clinical decision should the nurse make? Administer scheduled medications assuming that the NAP would have reported
- A. abnormal vital signs. Have the patient transported to the radiology department for a scheduled x-ray, and
- B. review vital signs upon return.
- C. Ask the NAP to record the patient’s vital signs before administering medications.
- D. Omit the vital signs because the patient is presently in no distress.
Correct Answer: C
Rationale: The correct answer is C because it is essential for the nurse to ensure accurate and up-to-date vital signs before administering medications. By asking the NAP to record the patient's vital signs, the nurse can make informed decisions about the patient's condition and prevent any potential complications.
Choice A is incorrect because administering medications without knowing the patient's vital signs, particularly if they are abnormal, can be dangerous. Choice B is not the best course of action as it delays the crucial step of obtaining the vital signs. Choice D is incorrect as omitting vital signs without assessment could compromise patient safety. Therefore, choice C is the most appropriate response to ensure patient well-being and medication safety.
