1. A client with amyotrophic lateral sclerosis (ALS) has been taking riluzole for two weeks. The nurse notes that the client remains weak with observable muscle atrophy. What action should the nurse take?
- A. Explain that the medication may take time to show improvement in symptoms
- B. Withhold the medication and notify the healthcare provider
- C. Advise the client to undergo liver function tests
- D. Document the assessment findings in the electronic health record
Correct answer: D
Rationale: In this scenario, the nurse's priority is to document the assessment findings in the electronic health record. This action is crucial for maintaining an accurate record of the client's health status and can provide valuable information for the healthcare team. While it is important to monitor the client's response to riluzole, explaining that the medication may take time to show improvement (Choice A) would be more appropriate if the client was expecting immediate results. Withholding the medication and notifying the healthcare provider (Choice B) should not be the initial action without further assessment or guidance. Advising the client to undergo liver function tests (Choice C) is not directly related to the current situation of weakness and muscle atrophy.
2. What is the most important action for the nurse to take to prevent infection in a client who has just returned from surgery with an indwelling urinary catheter in place?
- A. Change the catheter every 72 hours.
- B. Ensure the catheter tubing is free of kinks.
- C. Clean the perineal area with antiseptic solution daily.
- D. Irrigate the catheter with normal saline every shift.
Correct answer: B
Rationale: The most important action to prevent infection in a client with an indwelling urinary catheter is to ensure the catheter tubing is free of kinks. This action helps prevent obstruction, ensures proper drainage, and reduces the risk of infection. Changing the catheter every 72 hours is not necessary unless clinically indicated and may introduce unnecessary risk. Cleaning the perineal area with antiseptic solution daily is important for general hygiene but not the most critical action for catheter-related infection prevention. Irrigating the catheter with normal saline every shift is not a routine nursing intervention for catheter care and may increase the risk of introducing pathogens.
3. A young adult male with a history of substance abuse is admitted to the psychiatric unit for detoxification. He is agitated, sweating, and reports seeing bugs crawling on the walls. What is the priority nursing intervention?
- A. Reassure the client that the bugs are not real.
- B. Administer the prescribed benzodiazepine.
- C. Place the client in a quiet, dark room.
- D. Encourage the client to express his feelings.
Correct answer: B
Rationale: The correct answer is to administer the prescribed benzodiazepine. This intervention helps manage the client's agitation and hallucinations, which are common symptoms during detoxification from substances. Reassuring the client that the bugs are not real (Choice A) may not be effective in addressing the underlying causes of the hallucinations. Placing the client in a quiet, dark room (Choice C) may help reduce sensory stimulation but does not directly address the client's symptoms. Encouraging the client to express his feelings (Choice D) is important for therapeutic communication but may not be the priority when the client is experiencing severe agitation and hallucinations.
4. A child undergoes heart surgery to repair the defects associated with tetralogy of Fallot. What behavior is essential for the nurse to prevent postoperatively?
- A. Crying
- B. Coughing
- C. Straining at stool
- D. Unnecessary movement
Correct answer: C
Rationale: The correct behavior that the nurse needs to prevent postoperatively is straining at stool. Straining at stool should be avoided as it can increase intrathoracic pressure, leading to stress on the surgical site. This stress can potentially compromise the surgical repair and increase the risk of complications. Crying, coughing, and unnecessary movement, although important to monitor postoperatively, do not directly impact the surgical site as significantly as straining at stool does. Therefore, the focus should be on preventing straining at stool to ensure the best postoperative outcome for the child.
5. Which type of Leukocyte is involved with allergic responses and the destruction of parasitic worms?
- A. Neutrophils
- B. Lymphocytes
- C. Eosinophils
- D. Monocytes
Correct answer: C
Rationale: Eosinophils are the correct answer. Eosinophils are specialized white blood cells that play a crucial role in allergic responses and combating parasitic infections. They release substances to destroy parasites and modulate allergic reactions. Neutrophils (Choice A) are mainly involved in fighting bacterial infections. Lymphocytes (Choice B) play a key role in the immune response, including antibody production, but are not primarily responsible for combating parasites or allergic responses. Monocytes (Choice D) are involved in immune defense, differentiating into macrophages or dendritic cells, but they are not mainly associated with allergic responses or parasitic worm destruction.
