Nursing Elites

1. A client's laboratory findings indicate elevations in thyroxine and triiodothyronine hormones. The nurse suspects that the client may have hyperthyroidism. Which assessment finding is most often associated with hyperthyroidism?

• A. Periorbital edema.
• B. Atrophied thyroid gland.
• C. Increased pulse rate.
• D. Diarrhea stools.

Correct answer: C

Rationale: Increased pulse rate is commonly associated with hyperthyroidism due to the increased metabolic rate. Periorbital edema (Choice A) is more commonly associated with conditions like nephrotic syndrome or heart failure, not hyperthyroidism. Atrophied thyroid gland (Choice B) is not typically an assessment finding for hyperthyroidism as the gland is usually enlarged in this condition. Diarrhea stools (Choice D) can occur in hyperthyroidism, but it is not the most common assessment finding associated with the condition.

2. A client who underwent preadmission testing 1 week before surgery had blood drawn for several serum laboratory studies. Which abnormal laboratory results should the nurse report to the surgeon’s office? Select all that apply.

• A. Hematocrit 30%
• B. Sodium 141 mEq/L
• C. Hemoglobin 8.9 g/dL
• D. Platelets 210,000 cells/mm3

Correct answer: C

Rationale: The correct answer is C. Hemoglobin level of 8.9 g/dL is below the normal range, indicating anemia. Anemia can affect the body's ability to carry oxygen, impacting surgical outcomes. Hematocrit level is an indirect measure of red blood cells, which also reveals anemia when low. Sodium level of 141 mEq/L and platelet count of 210,000 cells/mm3 are within normal ranges and do not require immediate reporting. Abnormal sodium levels can lead to various issues, but in this scenario, it is not a concern for surgical readiness. Platelet count is vital for blood clotting, and a count of 210,000 cells/mm3 is considered normal, so it does not need urgent attention.

3. Which of the following is a priority intervention for a patient with heart failure?

• A. Administering diuretics.
• B. Administering oxygen.
• C. Administering beta-blockers.
• D. Administering vasodilators.

Correct answer: B

Rationale: Administering oxygen is a priority intervention in heart failure because it helps improve oxygenation, alleviate hypoxemia, and reduce the workload on the heart. Oxygen therapy is crucial in managing acute heart failure exacerbations. While diuretics (Choice A) are commonly used in heart failure to reduce fluid overload, administering oxygen takes precedence due to its immediate impact on oxygen delivery. Beta-blockers (Choice C) and vasodilators (Choice D) are also important in heart failure management, but in the acute setting, ensuring adequate oxygen supply is the priority.

4. 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.

5. Why is the combination drug trimethoprim-sulfamethoxazole (TMP-SMX) necessary?

• A. To broaden the antibacterial spectrum.
• B. To decrease bacterial resistance.
• C. To improve the taste.
• D. To minimize toxic effects.

Correct answer: B

Rationale: The correct answer is B: To decrease bacterial resistance. Trimethoprim-sulfamethoxazole (TMP-SMX) is a combination drug used to prevent bacterial resistance to sulfonamides. It works by targeting different steps in the bacterial metabolic pathway, making it harder for bacteria to develop resistance. Choice A is incorrect because the combination does not broaden the antibacterial spectrum; instead, it enhances effectiveness against specific bacteria. Choice C is incorrect as taste improvement is not the primary reason for combining these drugs. Choice D is incorrect because while combination therapy can sometimes help minimize toxic effects, the primary purpose in this case is to address bacterial resistance.
