Health Promotion and Maintenance NCLEX RN Questions

1. A client with hyperkalemia may exhibit peaked T waves on an electrocardiogram. This manifestation is an early sign of high potassium levels, but the diagnosis should not be based on this aspect alone. Untreated, hyperkalemia can lead to progressively worsening cardiac instability.

A. A lumbar puncture takes a sample of cerebrospinal fluid from the back, which will be analyzed by the lab.
B. The physician will insert a needle at the level of L4-L5 in the spinal cord.
C. The client should lie flat on their back for a specific period following the procedure.
D. The risks of the procedure include headache, back pain, and infection.

Correct answer: B

Rationale: A lumbar puncture is performed to obtain cerebrospinal fluid for analysis to investigate various conditions affecting the client. During the procedure, the client is typically positioned on their side or sitting leaning over a table with their back rounded. The physician inserts a needle into the back around the L4-L5 vertebrae to collect the sample. Option A is incorrect because a lumbar puncture does not draw blood but instead collects cerebrospinal fluid. Option C is incorrect as the client should not necessarily lie flat for 24 hours post-procedure. Option D is incorrect as the common risks of a lumbar puncture include headache, back pain, and potential infection, not nausea, rash, or hypotension.

2. What is the highest priority for post ECT care?

A. Observe for confusion
B. Monitor respiratory status
C. Reorient to time, place, and person
D. Document the client's response to the treatment

Correct answer: B

Rationale: The highest priority for post ECT care is to monitor respiratory status. This is crucial because a life-threatening side effect of ECT is respiratory arrest. While observing for confusion and reorienting the client are important aspects of post ECT care, they are not as critical as ensuring the client's respiratory status is stable. Documenting the client's response to treatment is also important for maintaining accurate medical records, but it is not the highest priority immediately post ECT.

3. What consideration is important when caring for a female Muslim patient?

A. Make eye contact
B. Provide long-sleeved gowns or allow her to use her own
C. Touch while talking
D. Assign male caregivers when possible

Correct answer: B

Rationale: When caring for a female Muslim patient, providing long-sleeved gowns or allowing her to use her own clothing is crucial. Most Muslim women prefer to cover their whole body, even during examinations. Offering long gowns with long sleeves or allowing the patient to use her own clothing respects her cultural and religious preferences. Making eye contact is not a common practice in some Muslim cultures, so it's important to be mindful of this and respect the patient's preferences. Touching while talking may not be culturally appropriate for some Muslim patients, so it's best to avoid it unless necessary. Assigning female caregivers is often preferred to respect the patient's modesty and religious beliefs. If a male caregiver or physician needs to interact with the patient, the patient's husband may request to be present in the room.

4. A client with asthma is being admitted for breathing difficulties. His arterial blood gas results are pH 7.26, PCO2 49, PaO2 90, and HCO3- 21. Which of the following best describes this condition?

A. Uncompensated respiratory acidosis
B. Compensated respiratory alkalosis
C. Uncompensated metabolic acidosis
D. Compensated metabolic alkalosis

Correct answer: A

Rationale: In this case, the client's arterial blood gas results show a pH of 7.26 and a PCO2 of 49, both of which are abnormal. A pH below the normal range of 7.35-7.45 indicates acidosis. The elevated PCO2 of 49 mmHg suggests respiratory acidosis as the primary issue. The normal range for PCO2 is 35-45 mmHg, so a value of 49 indicates the retention of excess CO2, leading to acidosis. The low HCO3- level of 21 also supports the presence of metabolic acidosis; however, the primary abnormality is respiratory, making this an uncompensated respiratory acidosis. Therefore, the correct answer is 'Uncompensated respiratory acidosis.' Choice B, 'Compensated respiratory alkalosis,' is incorrect because the client's pH is acidic, not alkalotic. Additionally, there is no compensation occurring for the primary respiratory acidosis indicated by the elevated PCO2. Choice C, 'Uncompensated metabolic acidosis,' is incorrect because while the HCO3- level is low, the primary issue indicated by the elevated PCO2 is respiratory acidosis. Choice D, 'Compensated metabolic alkalosis,' is incorrect since the arterial blood gas results do not support a metabolic alkalosis. The low HCO3- level would typically be seen in metabolic acidosis, but in this case, the primary issue is respiratory acidosis.

5. Becky is a 17-year-old type I diabetic who has been admitted for her third episode of diabetic ketoacidosis (DKA) since being diagnosed last year. She states that she hates feeling different from her friends and refuses to take her insulin as recommended. What would be the most helpful action for Becky?

A. Scolding her for not taking her insulin
B. Recommending that she use an insulin pump
C. Contacting the local support group for diabetic teens
D. Telling her parents they must provide more strict oversight

Correct answer: C

Rationale: Contacting the local support group for diabetic teens would be the most helpful action for Becky. By reaching out to see if another diabetic teenager could provide support, Becky would have the opportunity to connect with someone in her peer group who faces similar challenges. This connection can help reduce her sense of isolation and the feeling of being 'different.' Choice A, 'Scolding her for not taking her insulin,' is inappropriate and could further alienate Becky. It does not address the underlying emotional issues driving her behavior. Choice B, 'Recommending that she use an insulin pump,' does not directly address Becky's emotional struggle with feeling different from her friends. While an insulin pump may be a helpful tool, it does not tackle the root cause of her non-compliance. Choice D, 'Telling her parents they must provide more strict oversight,' focuses on imposing stricter control without addressing Becky's emotional needs or offering peer support, which may not be effective in improving her insulin adherence in the long term.
