Question 1 of 5
The nurse caring for a client in shock recognizes that the glomerular filtration rate of the kidneys will fail if the client's mean arterial pressure falls below which of the following levels?
Correct Answer: D
Rationale: A mean arterial pressure (MAP) below 80 mmHg compromises renal perfusion, leading to glomerular filtration failure. Higher MAPs (A, B,
C) maintain adequate kidney function.
Question 2 of 5
The physician has ordered a paracentesis for a client with severe abdominal ascites. Before the procedure, the nurse should:
Correct Answer: A
Rationale: Providing a urinal ensures the bladder is empty, reducing the risk of bladder puncture during paracentesis, a priority before the procedure.
Question 3 of 5
A client with vaginal cancer is being treated with a radioactive vaginal implant. The client's husband asks the nurse if he can spend the night with his wife. The nurse should explain that:
Correct Answer: D
Rationale: Radioactive implants emit radiation posing a risk to others. Visitation is limited to short periods (e.g. 30 minutes) to minimize radiation exposure. The other options do not address the safety concern related to radiation.
Question 4 of 5
Often children are monitored with pulse oximeter. The pulse oximeter measures the:
Correct Answer: B
Rationale: The O2 content of whole blood is determined by the partial pressure of oxygen (PO2) and the oxygen saturation. The pulse oximeter does not measure the PO2. The pulse oximeter is a noninvasive method of measuring the arterial oxygen saturation. The PO2 is the amount of O2 dissolved in plasma, which the pulse oximeter does not measure. The affinity of hemoglobin for O2 is the relationship between oxygen saturation and PO2 and is not measured by the pulse oximeter.
Question 5 of 5
A 4-year-old child has Down syndrome. The community health nurse has coordinated a special preschool program. The nurse's primary goal is to:
Correct Answer: B
Rationale: The primary goal for a child with Down syndrome is to facilitate optimal growth and development through tailored interventions.
