Nursing Elites

1. A nurse is teaching a class about immune deficiencies, and a person from the audience asks which cells are affected by severe combined immune deficiency (SCID) syndrome, and the nurse answers:

• A. B cell deficits
• B. T cell deficits
• C. Complement deficits
• D. B and T cell deficits

Correct answer: D

Rationale: The correct answer is D: B and T cell deficits. Severe combined immune deficiency (SCID) syndrome affects both B and T cells, leading to a severe impairment in the immune system's ability to fight infections. Choice A (B cell deficits) is incorrect because SCID affects not only B cells but also T cells. Choice B (T cell deficits) is incorrect as SCID is characterized by deficits in both B and T cells. Choice C (Complement deficits) is incorrect as SCID primarily involves B and T cell deficiencies rather than complement deficiencies.

2. A patient is receiving intravenous amphotericin. Which of the following assessments warrants the discontinuation of the antifungal agent?

• A. Sodium level of 138 mEq/L
• B. Hematocrit of 39%
• C. Blood urea nitrogen of 60 mg/dL
• D. AST level of 10 Unit/L

Correct answer: C

Rationale: Intravenous amphotericin can cause nephrotoxicity, leading to increased blood urea nitrogen levels. Elevated blood urea nitrogen (BUN) indicates impaired renal function, which is a known adverse effect of amphotericin. Therefore, a BUN level of 60 mg/dL warrants the discontinuation of the antifungal agent. The other options, such as a sodium level of 138 mEq/L, hematocrit of 39%, and AST level of 10 Unit/L, are within normal ranges and not indicative of the need to discontinue amphotericin therapy.

3. Thrombocytopenia is which disorder below?

• A. Increased blood coagulation
• B. Increased platelet production
• C. Increased number of infections
• D. Decreased platelet production

Correct answer: D

Rationale: Thrombocytopenia is a disorder characterized by a decreased platelet count or decreased platelet production, which affects blood clotting. Choice A, 'Increased blood coagulation,' is incorrect as thrombocytopenia is associated with decreased platelets, leading to impaired clotting. Choice B, 'Increased platelet production,' is incorrect as thrombocytopenia is characterized by a decrease in platelet production. Choice C, 'Increased number of infections,' is unrelated to thrombocytopenia, which primarily involves low platelet levels.

4. During admission, 82-year-old Mr. Robeson is brought to the medical-surgical unit for diagnostic confirmation and management of probable delirium. Which statement by the client’s daughter best supports the diagnosis?

• A. “Maybe it’s just caused by aging. This usually happens by age 82.”
• B. “The changes in his behavior came on so quickly! I wasn’t sure what was happening.”
• C. “Dad just didn’t seem to know what he was doing. He would forget what he had for breakfast.”
• D. “Dad has always been so independent. He’s lived alone for years since mom died.”

Correct answer: B

Rationale: The correct answer is B because sudden onset of behavioral changes is a typical symptom of delirium. Delirium is characterized by an acute and fluctuating disturbance in attention, awareness, and cognition. Choice A is incorrect because delirium is not a normal part of aging. Choice C describes memory issues, which can be seen in delirium but are less specific than sudden behavioral changes. Choice D, while it mentions the patient's independence, does not directly support the diagnosis of delirium.

5. What is a potential implication of multiple dark bands on the nails?

• A. They are considered a normal variant.
• B. They can be associated with malignant melanoma.
• C. They are indicative of a nail fungus.
• D. They are associated with aging.

Correct answer: B

Rationale: Multiple dark bands on the nails can be a concerning sign of malignant melanoma, a type of skin cancer that can affect the nails. While some nail changes are considered normal variants, dark bands should not be dismissed lightly as they can indicate a serious condition like melanoma. Nail fungus typically presents differently, causing discoloration, thickening, or distortion of the nail without distinct dark bands. Additionally, aging can lead to various nail changes, but dark bands alone are not a common feature of normal aging.
