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 has had two episodes of bacterial cystitis in the last 6 months is being assessed by a nurse. Which questions should the nurse ask? (Select all that apply.)
- A. How much water do you drink every day?
- B. Do you take estrogen replacement therapy?
- C. Does anyone in your family have a history of cystitis?
- D. All of the Above
Correct answer: D
Rationale: The correct answers are all of the above (D). Asking about fluid intake (choice A) is important as it can affect the risk of cystitis. Estrogen levels (choice B) can also impact the likelihood of recurrent cystitis. Family history (choice C) is relevant as certain genetic factors can predispose individuals to cystitis. Cranberry juice, not grapefruit or orange juice, has been found to reduce the risk of bacterial cystitis by increasing the acidic pH. Therefore, choices A, B, and C are all pertinent questions to ask during the assessment of a client with recurrent bacterial cystitis.
3. An emergency department nurse assesses a client with kidney trauma and notes that the client’s abdomen is tender and distended, and blood is visible at the urinary meatus. Which prescription should the nurse consult the provider about before implementation?
- A. Assessing vital signs every 15 minutes
- B. Inserting an indwelling urinary catheter
- C. Administering intravenous fluids at 125 mL/hr
- D. Typing and crossmatching for blood products
Correct answer: B
Rationale: In a client with kidney trauma and blood visible at the urinary meatus, inserting a urinary catheter via the urethra should be avoided until further diagnostic studies are completed to prevent potential urethral tears. The nurse should consult the provider about the need for a catheter; if necessary, a suprapubic catheter can be used instead. Assessing vital signs every 15 minutes is important for continuous monitoring of the client's condition. Administering intravenous fluids at 125 mL/hr is crucial to maintain hydration and support kidney function. Typing and crossmatching for blood products is necessary in case the client requires blood transfusion due to potential blood loss from the trauma.
4. In a patient with asthma, which of the following is the most important indicator of respiratory function?
- A. Oxygen saturation.
- B. Respiratory rate.
- C. Arterial blood gases.
- D. Peak expiratory flow rate.
Correct answer: D
Rationale: The peak expiratory flow rate is the most important indicator of respiratory function in asthma because it measures how quickly air can be exhaled, reflecting the severity of airflow limitation. Oxygen saturation (Choice A) is important in assessing oxygenation, but it does not directly reflect respiratory function. Respiratory rate (Choice B) can provide information on breathing patterns but does not quantify airflow limitation. Arterial blood gases (Choice C) give information about gas exchange but are not as specific for assessing asthma control and severity as peak expiratory flow rate.
5. A client who underwent surgery and experienced significant blood loss is being cared for by a nurse. Which findings by the nurse should prompt immediate action to prevent acute kidney injury? (Select all that apply.)
- A. Urine output of 100 mL in 4 hours
- B. Large amount of sediment in the urine
- C. A & B
- D. Amber, odorless urine
Correct answer: C
Rationale: The nurse must monitor for signs of acute kidney injury in a postoperative client who had major blood loss. Low urine output, presence of sediment in the urine, and low blood pressure should raise concerns and be reported to the healthcare provider promptly. Postoperatively, assessing urine characteristics is crucial. Sediment, hematuria, and urine output less than 0.5 mL/kg/hour for 3 to 4 hours should be reported. While a urine output of 100 mL in 4 hours is low, it should be compared to the recommended 0.5 mL/kg/hour over a longer period. Perfusion to the kidneys is a priority, hence the importance of addressing low blood pressure. Amber, odorless urine is considered normal and does not indicate an immediate concern for acute kidney injury, unlike low urine output and presence of sediment.
