Nursing Elites

1. Which lab value is a priority for a patient with HIV?

• A. CD4 T-cell count 180 cells/mm3
• B. Albumin levels below 3.5 g/dL
• C. Potassium levels below 3.5 mEq/L
• D. White blood cell count below 5000/mm3

Correct answer: A

Rationale: A CD4 T-cell count of less than 180 cells/mm3 is a priority for a patient with HIV because it indicates severe immunocompromise and an increased risk for opportunistic infections. Monitoring CD4 levels helps in assessing the immune status and guiding treatment decisions in patients with HIV. Albumin levels (choice B) are important for assessing nutritional status but are not a direct indicator of immune function in HIV patients. Potassium levels (choice C) and white blood cell count (choice D) are also important, but the CD4 T-cell count is specifically crucial for evaluating the immune function in individuals with HIV.

2. A nurse is assessing a client who has a sodium level of 122 mEq/L. Which of the following findings should the nurse expect?

• A. Decreased deep tendon reflexes
• B. Positive Chvostek's sign
• C. Hyperactive bowel sounds
• D. Dry mucous membranes

Correct answer: A

Rationale: Corrected deep tendon reflexes occur with hyponatremia. Other manifestations of hyponatremia include headache, confusion, lethargy, fatigue, seizures, and muscle weakness. Positive Chvostek's sign is associated with hypocalcemia, hyperactive bowel sounds are not typically related to hyponatremia, and dry mucous membranes are more commonly seen with dehydration.

3. What does continuous bubbling in the water seal chamber of a chest tube indicate?

• A. An air leak
• B. A blocked chest tube
• C. Normal chest tube function
• D. Continuous drainage from the chest tube

Correct answer: A

Rationale: Continuous bubbling in the water seal chamber of a chest tube indicates an air leak in the system. This occurs when air is entering the system through a leak, preventing the lung from fully re-expanding. Choice B, a blocked chest tube, is incorrect as a blocked tube would result in a lack of drainage rather than continuous bubbling. Choice C, normal chest tube function, is incorrect as continuous bubbling signifies an issue. Choice D, continuous drainage from the chest tube, is incorrect as bubbling in the water seal chamber specifically indicates an air leak, not just the presence of drainage.

4. What is the preferred treatment for a patient with unstable angina admitted with chest pain?

• A. Administer sublingual nitroglycerin
• B. Establish IV access
• C. Auscultate heart sounds
• D. Obtain cardiac enzymes

Correct answer: A

Rationale: The correct answer is to administer sublingual nitroglycerin. Nitroglycerin helps vasodilate coronary arteries, improving blood flow to the heart, relieving chest pain, and preventing cardiac tissue damage. Establishing IV access (choice B) is important but not the preferred initial treatment for unstable angina with chest pain. Auscultating heart sounds (choice C) and obtaining cardiac enzymes (choice D) are relevant assessments but do not address the immediate symptomatic relief needed for a patient with unstable angina and chest pain.

5. What lab value should be prioritized in a patient with HIV?

• A. CD4 T-cell count below 180 cells/mm3
• B. White blood cell count
• C. Serum albumin levels
• D. Hemoglobin levels

Correct answer: A

Rationale: The correct answer is A: CD4 T-cell count below 180 cells/mm3. Monitoring the CD4 T-cell count is crucial in patients with HIV as it indicates the level of immunocompromise. A count below 180 cells/mm3 signifies severe immunocompromise and an increased risk of opportunistic infections. Choices B, C, and D are not the priority lab values in HIV management. While white blood cell count, serum albumin levels, and hemoglobin levels are important, they do not directly reflect the immune status and progression of HIV as the CD4 T-cell count does.
