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 has lost a significant amount of blood due to complications during surgery. What parameter does the nurse recognize as the earliest indication of new decreases in fluid volume?

• A. Pulse rate
• B. Blood pressure
• C. Pulmonary artery systolic pressure
• D. Pulmonary artery end-diastolic pressure

Correct answer: A

Rationale: The earliest indication of new decreases in fluid volume is often recognized by an increase in pulse rate. Cardiac output is influenced by circulating blood volume, heart pumping action, and vascular tone. As fluid volume decreases, the body compensates by increasing the pulse rate. The formula for cardiac output is pulse rate multiplied by stroke volume. An elevated pulse rate helps maintain blood pressure with minor volume depletion. Pulmonary artery systolic pressure and pulmonary artery end-diastolic pressure, obtained through a pulmonary artery catheter, provide insights into pulmonary artery and left ventricle pressures at the end of diastole. These parameters are not the earliest indicators of new decreases in fluid volume compared to pulse rate.

3. When assessing an individual with peripheral vascular disease, which clinical manifestation would indicate complete arterial obstruction in the lower left leg?

• A. Aching pain in the left calf.
• B. Burning pain in the left calf.
• C. Numbness and tingling in the left leg.
• D. Coldness of the left foot and ankle.

Correct answer: D

Rationale: Coldness of the left foot and ankle is the correct clinical manifestation indicating complete arterial obstruction in the lower left leg. Complete arterial obstruction results in reduced blood flow, leading to decreased temperature in the affected area. Aching pain (Choice A) and burning pain (Choice B) are more commonly associated with partial obstructions or ischemia, while numbness and tingling (Choice C) can be indicative of nerve involvement or compromised circulation, but not specifically complete arterial obstruction. The coldness in the foot and ankle is a result of severely reduced blood flow, which impairs the delivery of oxygen and nutrients to the tissues in that area, leading to a lower temperature. This symptom is a critical indicator of a more severe blockage compared to the other options provided.

4. A client who has just undergone a skin biopsy is listening to discharge instructions from the nurse. The nurse determines that the client has misunderstood the directions if the client indicates that as part of aftercare he plans to:

• A. Use the antibiotic ointment as prescribed
• B. Return in 7 days to have the sutures removed
• C. Apply cool compresses to the site twice a day for 20 minutes
• D. Call the physician if excessive drainage from the wound occurs

Correct answer: C

Rationale: The correct answer is C. Applying cool compresses to the site twice a day for 20 minutes is not a recommended aftercare practice for a skin biopsy. After a skin biopsy, it is important to keep the dressing dry and in place for a minimum of 8 hours. Choice A is correct as using the antibiotic ointment as prescribed is a common post-biopsy instruction to prevent infection. Choice B is also correct as returning in 7 days to have the sutures removed is part of the typical follow-up care after a skin biopsy. Choice D is correct as it is important to call the physician if excessive drainage from the wound occurs to prevent complications.

5. A 58-year-old client who has been post-menopausal for five years is concerned about the risk for osteoporosis because her mother has the condition. Which information should the nurse offer?

• A. Osteoporosis is a progressive genetic disease with no effective treatment.
• B. Calcium loss from bones can be slowed by increasing calcium intake and exercise.
• C. Estrogen replacement therapy should be started to prevent the progression of osteoporosis.
• D. Low-dose corticosteroid treatment effectively halts the course of osteoporosis.

Correct answer: B

Rationale: Post-menopausal females are at risk for osteoporosis due to the cessation of estrogen secretion. While genetics can play a role, osteoporosis is not solely a genetic disease. Increasing calcium intake, along with vitamin D supplementation and weight-bearing exercise, can help prevent further bone loss by slowing down calcium loss from bones. Estrogen replacement therapy is no longer recommended as a first-line treatment for osteoporosis due to associated risks. Corticosteroid treatment is not typically used as a primary treatment for osteoporosis.
