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. A client who is receiving chemotherapy asks the nurse, 'Why is so much of my hair falling out each day?' Which response by the nurse best explains the reason for alopecia?

• A. 'Chemotherapy affects the cells of the body that grow rapidly, both normal and malignant.'
• B. 'Alopecia is a common side effect you will experience during long-term steroid therapy.'
• C. 'Your hair will grow back completely after your course of chemotherapy is completed.'
• D. 'The chemotherapy causes permanent alterations in your hair follicles that lead to hair loss.'

Correct answer: A

Rationale: The correct answer is A: 'Chemotherapy affects the cells of the body that grow rapidly, both normal and malignant.' Chemotherapy targets rapidly dividing cells, which include not only cancer cells but also healthy cells like those in hair follicles. This leads to alopecia (hair loss) as a common side effect. Choice B is incorrect as alopecia is primarily associated with chemotherapy and not long-term steroid therapy. Choice C is incorrect because while hair may grow back after chemotherapy, it may not always be to the same extent or thickness. Choice D is incorrect as chemotherapy-induced hair loss is often temporary and reversible, not permanent alterations in hair follicles.

3. To reduce the risk of pulmonary complications for a client with ALS, which intervention should the nurse implement?

• A. Perform chest physiotherapy
• B. Teach the client breathing exercises
• C. Initiate passive range of motion exercises
• D. Establish a regular bladder routine

Correct answer: A

Rationale: Performing chest physiotherapy is the most appropriate intervention to reduce the risk of pulmonary complications in clients with ALS. Chest physiotherapy helps mobilize and clear respiratory secretions, improving lung function and reducing the risk of complications such as pneumonia. Teaching breathing exercises (Choice B) may be beneficial for some clients, but chest physiotherapy is more specifically targeted at managing pulmonary issues in ALS. Initiating passive range of motion exercises (Choice C) and establishing a regular bladder routine (Choice D) are important interventions in ALS care but are not directly related to reducing the risk of pulmonary complications.

4. A healthcare professional reviews a client’s laboratory results. Which results from the client’s urinalysis should the healthcare professional identify as normal? (Select all that apply.)

• A. pH: 6
• B. Specific gravity: 1.015
• C. Glucose: negative
• D. All of the above

Correct answer: D

Rationale: In a urinalysis, a pH of 6 is within the normal range (typically between 4.6 and 8); a specific gravity of 1.015 is considered normal (usually ranging between 1.005 to 1.030); and a negative glucose result is also normal. Therefore, choices A, B, and C are correct as they fall within the normal values for a urinalysis. Choices A, B, and C are the correct answers, as the pH, specific gravity, and glucose levels are within the normal range for a urinalysis. Choice D is correct because all the listed values are normal. Choices A, B, and C are the correct options as they meet the criteria for normal urinalysis values. The other choices do not fall within the normal range for a urinalysis.

5. A client with Diabetes Insipidus (DI) is being cared for by a nurse. Which data warrants the most immediate intervention by the nurse?

• A. Serum sodium of 185 mEq/L (185 mmol/L)
• B. Dry skin with poor skin turgor
• C. Apical rate of 110 beats per minute
• D. Polyuria and excessive thirst

Correct answer: A

Rationale: A serum sodium level of 185 mEq/L (185 mmol/L) is dangerously high and indicates severe dehydration, requiring immediate intervention to prevent neurological damage. The other options are not as critical as high serum sodium levels, which can lead to serious complications such as seizures, coma, and death if not promptly addressed. Dry skin with poor skin turgor and polyuria with excessive thirst are common findings in clients with Diabetes Insipidus and should be managed but do not pose an immediate threat to the client's life. An apical heart rate of 110 beats per minute may indicate tachycardia, which could be related to dehydration but is not as urgent as addressing the severe hypernatremia.
