Nursing Elites

1. A CD4+ lymphocyte count is performed on a client infected with HIV. The results of the test indicate a CD4+ count of 450 cells/L. The nurse interprets this test result as indicating:

• A. Improvement in the client
• B. The need for antiretroviral therapy
• C. The need to discontinue antiretroviral therapy
• D. An effective response to the treatment for HIV

Correct answer: B

Rationale: A CD4+ count of 450 cells/L is below the normal range (500-1600 cells/mcL), indicating a decline in immune function in the client. Antiretroviral therapy is recommended when the CD4+ count falls below 500 cells/mcL or below 25%, or when the client displays symptoms of HIV. Therefore, the interpretation of this test result suggests that the client requires antiretroviral therapy to manage the HIV infection. Choices A, C, and D are incorrect because a CD4+ count of 450 cells/L does not signify improvement, discontinuation of therapy, or an effective response to treatment for HIV.

2. A client with type 1 diabetes mellitus has a blood glucose level of 620 mg/dL. After the nurse calls the physician to report the finding and monitors the client closely for:

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: A

Rationale: In the scenario described, a client with a blood glucose level of 620 mg/dL and type 1 diabetes mellitus is at risk of developing metabolic acidosis. In type 1 diabetes, the lack of sufficient circulating insulin leads to an increase in blood glucose levels. As the body cells utilize all available glucose, the breakdown of fats for energy results in the production of ketones, leading to metabolic acidosis. Metabolic alkalosis, respiratory acidosis, and respiratory alkalosis are not typically associated with uncontrolled type 1 diabetes. Metabolic alkalosis is more commonly linked to conditions such as vomiting or excessive diuretic use, while respiratory acidosis and respiratory alkalosis are related to respiratory system imbalances in carbon dioxide levels.

3. A healthcare professional is reading the chest x-ray report of a client who has just been intubated. The report states that the tip of the endotracheal tube lies 1 cm above the carina. The healthcare professional interprets that the tube is positioned above:

• A. The first tracheal cartilaginous ring
• B. The point where the larynx connects to the trachea
• C. The bifurcation of the right and left main stem bronchi
• D. The area connecting the oropharynx to the laryngopharynx

Correct answer: C

Rationale: The carina is a cartilaginous ridge that separates the openings of the two main stem (right and left) bronchi. If an endotracheal tube is inserted past the carina, the tube will enter the right main stem bronchus due to the natural curvature of the airway. This positioning is dangerous as only the right lung will be ventilated. It can be identified as only the right lung will have breath sounds and rise and fall with ventilation. Choices A, B, and D are incorrect as they do not relate to the specific anatomical landmark mentioned in the scenario.

4. Angiotensin-converting enzyme (ACE) inhibitors may be prescribed for the client with diabetes mellitus to reduce vascular changes and possibly prevent or delay the development of:

• A. Chronic obstructive pulmonary disease (COPD).
• B. Pancreatic cancer.
• C. Renal failure.
• D. Cerebrovascular accident.

Correct answer: C

Rationale: The correct answer is C: Renal failure. ACE inhibitors are commonly used in clients with diabetes mellitus to help reduce the progression of diabetic nephropathy by improving renal blood flow. This medication class can help prevent or delay the development of renal failure in these clients. Choices A, B, and D are incorrect because ACE inhibitors do not have a direct impact on preventing or delaying the development of chronic obstructive pulmonary disease, pancreatic cancer, or cerebrovascular accidents in clients with diabetes mellitus.

5. To assess the quality of an adult client's pain, what approach should the nurse use?

• A. Observe body language and movement.
• B. Ask the client to describe the pain.
• C. Identify effective pain relief measures.
• D. Provide a numeric pain scale.

Correct answer: B

Rationale: The correct answer is to ask the client to describe the pain. This approach allows the nurse to gather subjective information directly from the client, such as the quality, intensity, location, and factors that aggravate or alleviate the pain. Observing body language and movement (Choice A) can provide additional cues but may not fully capture the client's pain experience. Identifying effective pain relief measures (Choice C) and providing a numeric pain scale (Choice D) are important aspects of pain management but do not directly assess the quality of the client's pain.
