Nursing Elites

1. 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.

2. The nurse is preparing to administer the first dose of hydrochlorothiazide (HydroDIURIL) 50 mg to a patient who has a blood pressure of 160/95 mm Hg. The nurse notes that the patient had a urine output of 200 mL in the past 12 hours. The nurse will perform which action?

• A. Administer the medication as ordered.
• B. Encourage the patient to drink more fluids.
• C. Hold the medication and request an order for serum BUN and creatinine.
• D. Request an order for serum electrolytes and administer the medication.

Correct answer: C

Rationale: The correct action is to hold the medication and request an order for serum BUN and creatinine. Thiazide diuretics, such as hydrochlorothiazide, are contraindicated in renal failure. In this case, the patient has oliguria, which is a reduced urine output, indicating potential renal insufficiency. Before administering the diuretic, it is crucial to evaluate the patient's renal function through serum BUN and creatinine levels. Encouraging the patient to drink more fluids (Choice B) may not address the underlying issue of renal function. Administering the medication as ordered (Choice A) without assessing renal function can be harmful. Requesting serum electrolytes and administering the medication (Choice D) overlooks the need for a specific evaluation of renal function in this scenario.

3. A client with cirrhosis develops increasing pedal edema and ascites. What dietary modification is most important for the nurse to teach this client?

• A. Avoid high carbohydrate foods.
• B. Decrease intake of fat-soluble vitamins.
• C. Decrease caloric intake.
• D. Restrict salt and fluid intake.

Correct answer: D

Rationale: The correct answer is to restrict salt and fluid intake. In clients with cirrhosis presenting with pedal edema and ascites, excessive fluid retention occurs, necessitating the restriction of salt and fluid to alleviate these symptoms. Choice A, avoiding high carbohydrate foods, is not the priority in this situation. Decreasing intake of fat-soluble vitamins (Choice B) is not specifically indicated for managing edema and ascites in cirrhosis. While maintaining an appropriate caloric intake is important, decreasing caloric intake (Choice C) is not the primary focus when addressing fluid retention in cirrhosis.

4. A client with early breast cancer receives the results of a breast biopsy and asks the nurse to explain the meaning of staging and the type of receptors found on the cancer cells. Which explanation should the nurse provide?

• A. Lymph node involvement is not significant.
• B. Small tumors are aggressive and indicate poor prognosis.
• C. The tumor's estrogen receptor guides treatment options.
• D. Stage I indicates metastasis.

Correct answer: C

Rationale: Treatment decisions and prediction of prognosis are related to the tumor's receptor status, such as estrogen and progesterone receptor status which commonly are well-differentiated, have a lower chance of recurrence, and are receptive to hormonal therapy. Tumor staging designates tumor size and spread of breast cancer cells into axillary lymph nodes, which is one of the most important prognostic factors in early-stage breast cancer.

5. When providing care for an unconscious client who has seizures, which nursing intervention is most essential?

• A. Ensure oral suction is available.
• B. Maintain the client in a semi-Fowler's position.
• C. Provide frequent mouth care.
• D. Keep the room at a comfortable temperature.

Correct answer: A

Rationale: During seizures in an unconscious client, ensuring oral suction is available is crucial to managing secretions and preventing aspiration. This intervention helps maintain a clear airway and reduce the risk of complications. Maintaining the client in a semi-Fowler's position (Choice B) may be important for airway management but is not as critical as having oral suction ready. Providing frequent mouth care (Choice C) and keeping the room at a comfortable temperature (Choice D) are important aspects of overall care but are not as urgently needed as ensuring oral suction for managing secretions during seizures.
