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.

A client has possible malignancy of the colon, and surgery is scheduled. The rationale for administering Neomycin preoperatively is to:
- A. Prevent infection postoperatively
- B. Eliminate the need for preoperative enemas
- C. Decreased and retard the growth of normal bacteria in the intestines
- D. Treat cancer of the colon
Correct Answer: C
Rationale: The correct answer is C because Neomycin is given preoperatively to decrease and retard the growth of normal bacteria in the intestines. This helps reduce the risk of infection during surgery by minimizing the number of bacteria present in the colon. Options A, B, and D are incorrect because Neomycin is not given to prevent infection postoperatively, eliminate the need for preoperative enemas, or treat cancer of the colon. The main purpose of administering Neomycin in this scenario is to create a sterile surgical field by reducing the normal flora in the intestines.
A nurse evaluates a client’s response to a nursing intervention and determines that the expected outcome was not achieved. What is the nurse’s most appropriate action?
- A. Terminate the plan of care
- B. Modify the plan of care
- C. Reassign care to another nurse
- D. Reassess the client’s condition
Correct Answer: D
Rationale: The correct answer is D: Reassess the client's condition. When an expected outcome is not achieved, the nurse must reassess the client's condition to identify the reasons for the lack of success. This step allows the nurse to gather more information, adjust the plan of care if necessary, and determine the most suitable course of action to help the client achieve the desired outcome.
Choice A: Terminating the plan of care is premature without reassessing the client's condition and identifying potential barriers to success.
Choice B: Modifying the plan of care may be necessary after reassessment but should not be the first step.
Choice C: Reassigning care to another nurse does not address the underlying issues affecting the client's response to the intervention.
A nurse is conducting a nursing health history. Which component will the nurse address?
- A. Nurse’s concerns
- B. Patient expectations
- C. Current treatment orders
- D. Nurse’s goals for the patient
Correct Answer: B
Rationale: The correct answer is B: Patient expectations. In a nursing health history, the nurse focuses on understanding the patient's expectations, needs, and preferences to provide patient-centered care. This step is essential for building rapport, establishing trust, and tailoring care plans to meet the patient's individual needs.
Incorrect choices:
A: Nurse’s concerns - This is not the primary focus during a nursing health history. The nurse should prioritize understanding the patient's perspective.
C: Current treatment orders - While important, this is typically addressed during the assessment phase, not specifically in the nursing health history.
D: Nurse’s goals for the patient - The nurse's goals should align with the patient's goals, making understanding the patient's expectations crucial.
Which of the ff. problems during the immediate postoperative course ff. lumbar microdiskectomy should be reported to the physician immediately?
- A. Incisional pain
- B. Inability to move affected leg
- C. Two-inch area of bleeding on dressing
- D. Muscle spasm of affected
Correct Answer: B
Rationale: The correct answer is B because the inability to move the affected leg post lumbar microdiskectomy could indicate a serious complication like nerve damage or blood clot. This would require immediate medical attention to prevent further complications. Incisional pain (A) is common and can be managed with pain medication. A two-inch area of bleeding on the dressing (C) is concerning but can be managed with proper wound care unless it is excessive. Muscle spasm (D) is also common postoperatively and can be managed with medications or physical therapy.
One of the dangers of treating hypernatremia is:
- A. Red blood cell crenation
- B. Cerebral edema
- C. Red blood cell hydrolysis
- D. Renal shutdown
Correct Answer: B
Rationale: The correct answer is B: Cerebral edema. Hypernatremia is an elevated sodium level in the blood, which can lead to osmotic shifts causing water to move out of cells, including brain cells. This can result in cerebral edema, potentially leading to neurological complications.
Incorrect choices:
A: Red blood cell crenation - This occurs in hypertonic solutions, not hypernatremia.
C: Red blood cell hydrolysis - Hypernatremia doesn't directly cause red blood cell hydrolysis.
D: Renal shutdown - Hypernatremia can stress the kidneys, but it doesn't typically lead to renal shutdown.
