Nursing Elites

1. A patient with a diagnosis of Cushing's syndrome is likely to exhibit which of the following symptoms?

• A. Hyperpigmentation.
• B. Moon face.
• C. Hypotension.
• D. Hypertension.

Correct answer: B

Rationale: The correct answer is B: Moon face. Cushing's syndrome is characterized by excess cortisol levels, leading to the distinctive round and full face known as moon face. Hyperpigmentation (choice A) may occur due to increased ACTH levels, but it is not a hallmark symptom like moon face. Hypotension (choice C) is less common in Cushing's syndrome as cortisol typically leads to hypertension (choice D) due to its effects on blood pressure regulation.

2. A client has had a pulmonary artery catheter inserted. In performing hemodynamic monitoring with the catheter, the nurse will wedge the catheter to gain information about which of the following?

• A. Cardiac output.
• B. Right atrial blood flow.
• C. Left end-diastolic pressure.
• D. Cardiac index.

Correct answer: C

Rationale: The correct answer is C: Left end-diastolic pressure. Wedging the pulmonary artery catheter allows the nurse to obtain the pulmonary artery wedge pressure, which reflects the left end-diastolic pressure. This pressure is essential in assessing left ventricular function and diagnosing conditions like heart failure. Choices A, B, and D are incorrect because wedging the catheter does not directly provide information about cardiac output, right atrial blood flow, or cardiac index.

3. Blood for arterial blood gas determinations is drawn from a client with pneumonia, and testing reveals a pH of 7.45, PCO2 of 30 mm Hg, and HCO3 of 19 mEq/L. The nurse interprets these results as indicative of:

• A. Compensated metabolic acidosis
• B. Compensated respiratory alkalosis
• C. Uncompensated metabolic alkalosis
• D. Uncompensated respiratory acidosis

Correct answer: B

Rationale: The correct answer is 'Compensated respiratory alkalosis.' In this case, the client's pH is within the normal range (7.35-7.45), indicating compensation. The low PCO2 (30 mm Hg) suggests respiratory alkalosis, while the low HCO3 (19 mEq/L) is also consistent with a compensatory response. Therefore, the client has a primary respiratory alkalosis that is being compensated for by metabolic acidosis. Choices A, C, and D are incorrect because they do not fit the pattern of the given blood gas values, which indicate respiratory alkalosis with metabolic compensation.

4. The nurse is administering intravenous fluids to a dehydrated patient. On the second day of care, the patient's weight has increased by 2.25 pounds. The nurse would expect that the patient's fluid intake has

• A. equaled urine output.
• B. exceeded urine output by 1 L.
• C. exceeded urine output by 2.5 L.
• D. exceeded urine output by 3 L.

Correct answer: B

Rationale: A weight gain of 1 kg, or approximately 2.2 to 2.5 lb, is generally equivalent to 1 liter (L) of fluid retained by the body. In this case, the patient's weight gain of 2.25 pounds suggests an excess fluid retention of approximately 1 liter, indicating that the patient's fluid intake has exceeded urine output by 1 liter. Choices C and D are incorrect as they overestimate the fluid excess based on the patient's weight gain. Choice A is incorrect as it implies an exact balance between fluid intake and urine output, which is not reflected in the given weight increase.

5. When preparing to examine a client’s skin using a Wood light, what should the nurse do to facilitate this procedure?

• A. Darken the examining room
• B. Administer a local anesthetic
• C. Obtain a signed informed consent
• D. Shave the skin and scrub it with povidone-iodine (Betadine)

Correct answer: A

Rationale: When using a Wood light to examine the skin, the nurse should darken the examining room. This is necessary because the Wood light emits long-wavelength UV light, which is better visualized in a darkened environment. Administering a local anesthetic (Choice B) is not needed for this procedure. Obtaining a signed informed consent (Choice C) is not directly related to using a Wood light for skin examination. Shaving the skin and scrubbing it with povidone-iodine (Betadine) (Choice D) is not required and may not be appropriate for this type of skin examination.
