Nursing Elites

1. A male client with acquired immune deficiency syndrome (AIDS) and Pneumocystis carinii pneumonia has a CD4+ T cell count of 200 cells/microliter. The client asks the nurse why he keeps getting these massive infections. Which pathophysiologic mechanism should the nurse describe in response to the client's question?

• A. Bone marrow suppression of white blood cells causes insufficient cells to phagocytize organisms.
• B. Exposure to multiple environmental infectious agents overburdens the immune system until it fails.
• C. The humoral immune response lacks B cells that form antibodies and opportunistic infections result.
• D. Inadequate numbers of T lymphocytes are available to initiate cellular immunity and macrophages.

Correct answer: D

Rationale: With a CD4+ T cell count of 200 cells/microliter, the client's immune system is severely compromised, leading to opportunistic infections.

2. A client with chronic obstructive pulmonary disease (COPD) presented with shortness of breath. Oxygen therapy was started at 2 liters/minute via nasal cannula. The arterial blood gases (ABGs) after treatment were pH 7.36, PaO2 52, PaCO2 59, HCO3 33. Which statement describes the most likely cause of the simultaneous increase in both PaO2 and PaCO2?

• A. The client is hyperventilating due to anxiety.
• B. The hypoxic drive was reduced by the oxygen therapy.
• C. The client is experiencing respiratory alkalosis.
• D. The client is experiencing metabolic acidosis.

Correct answer: B

Rationale: Oxygen therapy can reduce the hypoxic drive in COPD patients, leading to increased PaCO2 levels while improving oxygenation (PaO2). In this case, the increase in PaO2 and PaCO2 is due to the reduction of the hypoxic drive by the supplemental oxygen. Choice A is incorrect because hyperventilation would lead to decreased PaCO2. Choice C is incorrect as the ABG values do not indicate respiratory alkalosis. Choice D is incorrect as the ABG values do not support metabolic acidosis.

3. A client with fluid volume excess has gained 6.6 pounds. The nurse recognizes that this is equivalent to what volume of fluid?

• A. Two liters.
• B. Three liters.
• C. Four liters.
• D. Five liters.

Correct answer: B

Rationale: A weight gain of 6.6 pounds is approximately equivalent to 3 liters of fluid. It is important to remember that 1 liter of fluid is equal to 1 kg, which is approximately 2.2 pounds. Therefore, when the client gains 6.6 pounds, it translates to 3 liters of fluid. Choices A, C, and D are incorrect as they do not align with the conversion rate of 1 liter of fluid to 2.2 pounds.

4. A client who has a history of hyperthyroidism was initially admitted with lethargy and confusion. Which additional finding warrants the most immediate action by the nurse?

• A. Facial puffiness and periorbital edema
• B. Hematocrit of 30%
• C. Cold and dry skin
• D. Further decline in LOC

Correct answer: D

Rationale: A further decline in LOC can indicate severe complications and requires immediate attention. This change may signify worsening neurological status, which could lead to life-threatening consequences if not addressed promptly. Choices A, B, and C may also be concerning in a client with a history of hyperthyroidism, but a further decline in LOC takes priority due to its potential for rapid deterioration and the need for urgent intervention.

5. A client with a new colostomy is concerned about odor. What is the best advice the nurse can provide?

• A. Avoid high-fiber foods
• B. Use an odor-proof pouch
• C. Decrease fluid intake
• D. Increase dairy products in the diet

Correct answer: B

Rationale: The best advice the nurse can provide to a client concerned about odor from a new colostomy is to use an odor-proof pouch. This option helps control odors effectively by containing and masking any unpleasant smells. Avoiding high-fiber foods (Choice A) is not the best advice as fiber is essential for bowel health, and decreasing fluid intake (Choice C) can lead to dehydration and other complications. Increasing dairy products in the diet (Choice D) is not directly related to controlling odors from a colostomy.
