Nursing Elites

1. The nurse is evaluating the laboratory reports of a client with hypothyroidism. The nurse would expect which of the following laboratory values?

• A. Increased TSH
• B. Increased thyroxine (T4)
• C. Decreased TSH
• D. Decreased T3

Correct answer: A

Rationale: The correct answer is A: Increased TSH. In hypothyroidism, the thyroid gland is underactive, leading to low levels of thyroid hormones. As a compensatory mechanism, the pituitary gland releases more thyroid-stimulating hormone (TSH) to try to stimulate the thyroid gland to produce more hormones. Therefore, increased TSH levels are expected in hypothyroidism. Choice B is incorrect because in hypothyroidism, thyroxine (T4) levels are usually decreased, not increased. Choice C is incorrect as hypothyroidism is characterized by increased TSH levels, not decreased. Choice D is also incorrect because in hypothyroidism, T3 levels may be decreased, but TSH is a more sensitive indicator for diagnosis.

2. A client with diabetes mellitus presents with a blood sugar level of 320 mg/dL. What is the nurse's initial action?

• A. Administer sliding scale insulin as prescribed
• B. Encourage the client to drink fluids
• C. Provide the client with a carbohydrate snack
• D. Assess the client for signs of hypoglycemia

Correct answer: A

Rationale: When a client with diabetes mellitus presents with a high blood sugar level of 320 mg/dL, the nurse's initial action should be to administer sliding scale insulin as prescribed. The priority is to bring down the elevated glucose level promptly to prevent further complications. Encouraging the client to drink fluids or providing a carbohydrate snack would not effectively address the elevated blood sugar level in this scenario. Assessing for signs of hypoglycemia is not appropriate as the client's blood sugar level is high, not low.

3. The nurse is providing discharge teaching to a client with asthma. Which statement indicates the client understands how to use a rescue inhaler?

• A. I will use my rescue inhaler every morning to prevent asthma attacks.
• B. I should use my rescue inhaler when I start to experience wheezing.
• C. I will use my rescue inhaler when my peak flow meter reading is in the green zone.
• D. I will only use my rescue inhaler before going to bed.

Correct answer: B

Rationale: The correct answer is B: 'I should use my rescue inhaler when I start to experience wheezing.' A rescue inhaler is used during the onset of asthma symptoms, such as wheezing, to quickly open the airways. It is not intended for routine daily use or prevention, which is the role of a maintenance inhaler. Option A is incorrect because a rescue inhaler is not used for prevention but for immediate relief during an asthma attack. Option C is incorrect because the peak flow meter reading is used to monitor asthma control, not to determine when to use a rescue inhaler. Option D is incorrect because using a rescue inhaler only before going to bed does not address the need for immediate relief when wheezing or experiencing asthma symptoms.

4. A client with heart failure is prescribed furosemide. The nurse notes that the client's potassium level is 3.1 mEq/L. What is the nurse's priority action?

• A. Administer a potassium supplement
• B. Encourage the client to eat potassium-rich foods
• C. Hold the next dose of furosemide
• D. Increase the client's fluid intake

Correct answer: A

Rationale: A potassium level of 3.1 mEq/L is considered low, indicating hypokalemia. Administering a potassium supplement is the nurse's priority action to prevent complications such as cardiac arrhythmias associated with low potassium levels. Encouraging the client to eat potassium-rich foods is beneficial in the long term but may not rapidly correct the low potassium level. Holding the next dose of furosemide may worsen the client's heart failure symptoms. Increasing the client's fluid intake is not the priority action in this situation; addressing the low potassium level takes precedence to prevent potential serious complications.

5. After repositioning an immobile client, the nurse observes an area of hyperemia. What action should the nurse take to assess for blanching?

• A. Document the presence in the client’s record.
• B. Apply light pressure over the area.
• C. Apply heat to the area and reassess in 30 minutes.
• D. Apply cold compresses to reduce the redness.

Correct answer: B

Rationale: The correct action for the nurse to take to assess for blanching in an area of hyperemia is to apply light pressure over the area. Blanching is the temporary whitening of the skin when pressure is applied and then released, indicating that the blood flow is returning to the area. Applying light pressure helps in determining if the hyperemic area blanches, ensuring that blood flow is adequate. Choices A, C, and D are incorrect because documenting findings, applying heat, or using cold compresses are not appropriate actions for assessing blanching in an area of hyperemia.
