What is a causative factor of Hirschsprung disease?
- A. Frequent evacuation of solids, liquid, and gases
- B. Excessive peristaltic movement
- C. The absence of parasympathetic ganglion cells in a portion of the colon
- D. One portion of the bowel telescoping into another
Correct Answer: C
Rationale: The correct answer is C: The absence of parasympathetic ganglion cells in a portion of the colon is a causative factor of Hirschsprung disease. This absence leads to the inability of the affected segment of the colon to relax, causing a functional obstruction. Choices A, B, and D are incorrect. Frequent evacuation of solids, liquid, and gases, excessive peristaltic movement, and one portion of the bowel telescoping into another are not causative factors of Hirschsprung disease.

An overweight, young adult male who was recently diagnosed with type 2 diabetes mellitus is admitted for a hernia repair. He tells the nurse that he is feeling very weak and jittery. Which actions should the nurse implement? (Select all that apply)
- A. Check his fingerstick glucose
- B. Assess his skin temperature and moisture
- C. Measure his pulse and BP
- D. All of the Above
Correct Answer: D
Rationale: In this scenario, the patient is a young adult male with type 2 diabetes mellitus admitted for a hernia repair who is experiencing weakness and jitteriness. Checking his fingerstick glucose is crucial to assess his blood sugar levels, which can directly impact his symptoms. Assessing his skin temperature and moisture is important to evaluate his peripheral circulation and hydration status. Measuring his pulse and blood pressure helps in gauging his cardiovascular status. Therefore, all the actions mentioned in choices A, B, and C are appropriate for the nurse to implement in this situation to identify the underlying cause of the patient's symptoms. Choice D, 'All of the Above,' is the correct answer because all these actions are necessary for a comprehensive assessment of the patient's condition. Choices A, B, and C are incorrect individually as they each address different aspects of the patient's condition, and a holistic approach is needed to provide optimal care in this situation.
A client who took a camping vacation two weeks ago in a country with a tropical climate comes to the clinic describing vague symptoms and diarrhea for the past week. Which finding is most important for the nurse to report to the HCP?
- A. Weakness and fatigue
- B. Intestinal cramping
- C. Weight loss
- D. Jaundiced sclera
Correct Answer: D
Rationale: The most important finding to report to the healthcare provider is a jaundiced sclera. Jaundice suggests liver involvement, which can be a sign of a serious underlying condition. Weakness and fatigue, intestinal cramping, and weight loss are important symptoms, but jaundice indicates a more urgent issue that needs immediate attention.
A client with chronic heart failure is experiencing dyspnea and has an oxygen saturation of 88%. Which position is most appropriate to improve oxygenation?
- A. Supine with legs elevated
- B. High Fowler's position
- C. Prone with pillows under the chest
- D. Side-lying with head flat
Correct Answer: B
Rationale: The correct answer is B: High Fowler's position. High Fowler's position is the most appropriate for a client with chronic heart failure experiencing dyspnea and low oxygen saturation. This position helps improve lung expansion and oxygenation by maximizing chest expansion and allowing better ventilation. Choice A, supine with legs elevated, may worsen dyspnea by reducing lung expansion. Choice C, prone with pillows under the chest, is not suitable for a client experiencing dyspnea as it may further compromise breathing. Choice D, side-lying with head flat, does not facilitate optimal lung expansion and is not the best choice for improving oxygenation in this scenario.
After hospitalization for SIADH, a client develops pontine myelinolysis. Which intervention should the nurse implement first?
- A. Reorient the client to the room
- B. Place an eye patch on one eye
- C. Evaluate the client's ability to swallow
- D. Perform range of motion exercises
Correct Answer: C
Rationale: Evaluating the client's ability to swallow is the priority intervention in this scenario. Pontine myelinolysis can affect neurological functions, including swallowing ability, putting the client at risk for aspiration. Assessing the client's ability to swallow will help prevent complications such as aspiration pneumonia. Reorienting the client to the room, placing an eye patch, or performing range of motion exercises are not as critical as ensuring the client can safely swallow.
An adolescent female asks the nurse about taking retinoic acid (Accutane). What guidance should be provided by the nurse?
- A. The medication should be used for 10 weeks only.
- B. The medication requires that sexually active females use contraception.
- C. The medication lowers hemoglobin levels very quickly.
- D. The medication has few side effects.
Correct Answer: B
Rationale: The correct guidance the nurse should provide is that sexually active females must use contraception while taking Accutane and for 1 month after the 20 weeks it is prescribed. Choice A is incorrect because Accutane is typically taken for a longer duration than 10 weeks. Choice C is incorrect because Accutane does not lower hemoglobin levels quickly. Choice D is incorrect as Accutane is known for having many side effects, including the risk of birth defects.
