When caring for a client with diabetes insipidus, the nurse expects to administer:
- A. Vasopressin (Pitressin Synthetic)
- B. Regular insulin
- C. Furosemide (Lasix)
- D. 10% dextrose
Correct Answer: A
Rationale: The correct answer is A: Vasopressin (Pitressin Synthetic). In diabetes insipidus, there is a deficiency of ADH (antidiuretic hormone), leading to excessive urination and thirst. Vasopressin is a synthetic form of ADH that helps retain water by reducing urine output. Administering vasopressin helps manage the symptoms of diabetes insipidus.
B: Regular insulin is used to manage diabetes mellitus, not diabetes insipidus.
C: Furosemide is a diuretic used to increase urine output, which would worsen the symptoms of diabetes insipidus.
D: 10% dextrose is a form of glucose and is not indicated in the treatment of diabetes insipidus.

When testing visual fields, the nurse is assessing which of the following parts of vision?
- A. Peripheral vision
- B. Distance vision
- C. Near vision
- D. Central vision
Correct Answer: A
Rationale: The correct answer is A: Peripheral vision. When testing visual fields, the nurse evaluates the ability to see objects outside the direct line of sight, which is indicative of peripheral vision. Peripheral vision helps detect objects and movement in the side vision. Distance vision (B) refers to the ability to see clearly at a distance, while near vision (C) pertains to close-up vision. Central vision (D) is essential for focusing on details and seeing straight ahead. Therefore, A is the correct choice as it specifically pertains to the assessment of visual fields.
A client is diagnosed with megaloblastic anemia caused by vitamin B12 deficiency. The physician begins the client on cyanocobalamin (Betalin-12), 100mcg IM daily. Which substance influences Vitamin B12 absorption?
- A. Intrinsic factor
- B. Histamine
- C. Hydrochloric acid
- D. Liver enzyme
Correct Answer: A
Rationale: Rationale: Intrinsic factor is a glycoprotein produced by the stomach that is essential for the absorption of vitamin B12 in the ileum. Without intrinsic factor, vitamin B12 absorption is impaired, leading to megaloblastic anemia. Histamine and hydrochloric acid are not directly involved in vitamin B12 absorption. Liver enzymes are not implicated in the absorption process. Therefore, the correct answer is A.
Nurse Beverly is giving preoperative instructions to Ian who is scheduled for an Ileostomy. Which of the following would be included?
- A. “Your urine will be collected in a pouch following surgery.”
- B. “You will have a nasogastric tube after surgery.”
- C. “Your bowel will be visualized with a laparoscope during surgery.”
- D. “You can drink liquids within 24 hours after surgery.”
Correct Answer: A
Rationale: The correct answer is A because an Ileostomy involves diverting the small intestine to an opening in the abdominal wall, so the urine will not be affected. The pouch collects waste from the small intestine. Nasogastric tube (B) is not typically required for an Ileostomy. Laparoscope (C) is used for visualizing the abdomen, not the bowel. Drinking liquids (D) so soon after surgery can be risky and is not recommended.
Olympic gymnast Ms. Slovenski sufferd a great fall and suffered a great fall and fractured her femur. Approximately after 20 hours in the hospital she became dyspneic, tachypneic, and with scattered crackles in her lung fields. She is coughing up large amounts of thick, white sputum. The nurse correctly interprets this as:
- A. respiratory compromise related to inhalation of smoke
- B. pneumonia related to prolonged bedrest
- C. fat embolism syndrome related to femur fracture
- D. hypovolemic shock related to multiple trauma
Correct Answer: C
Rationale: The correct answer is C: fat embolism syndrome related to femur fracture. Fat embolism syndrome occurs when fat globules enter the bloodstream and travel to the lungs, causing respiratory distress. In this case, the patient's femur fracture likely led to fat embolism, explaining her dyspnea, tachypnea, crackles, and thick sputum. Choices A, B, and D do not align with the patient's presentation and history, making them incorrect. Choice A suggests smoke inhalation, which is not supported by the scenario. Choice B mentions pneumonia from bedrest, which is not a common complication of immobility. Choice D proposes hypovolemic shock from multiple trauma, which does not explain the respiratory symptoms and sputum production observed in the patient.
How many liters per minute of oxygen should be administered to the patient with emphysema?
- A. 2 L/min
- B. 10 L/min
- C. 6 L/min
- D. 95 L/min
Correct Answer: A
Rationale: The correct answer is A: 2 L/min. In emphysema, there is impaired gas exchange due to damaged lung tissue, resulting in decreased oxygen levels. Administering too high a flow rate can lead to oxygen toxicity. The standard oxygen therapy for emphysema is 1-2 L/min to maintain oxygen saturation without causing harm. Higher flow rates like 10 L/min (B) and 6 L/min (C) are excessive and can lead to oxygen toxicity. 95 L/min (D) is dangerously high and not suitable for oxygen therapy in emphysema. Therefore, A is the correct choice for safe and effective oxygen administration in emphysema.
