A normal glomerular filtration rate is
- A. less than 80 mL/min.
- B. 80 to 125 mL/min.
- C. 125 to 180 mL/min.
- D. more than 189 mL/min.
Correct Answer: B
Rationale: The correct answer is B (80 to 125 mL/min) because this range reflects the normal glomerular filtration rate (GFR) in adults. GFR measures the rate at which blood is filtered by the kidneys, typically around 125 mL/min. A GFR below 60 mL/min indicates kidney dysfunction, making option A incorrect. Option C (125 to 180 mL/min) is above the normal range. Option D (more than 189 mL/min) is too high and could indicate hyperfiltration, common in conditions like diabetes. Therefore, choice B is the most appropriate within the normal GFR range.

A patient is transferred to the ICU from the Birth Center of the hospital in the middle of the night after experiencing complications during delivery of her baby. The patients husband is anxious and explains to the ICU nurse that he doesnt understand why his wife has been moved to the ICU. She is going to die, isnt she? he asks the nurse. What is the nurses best response?
- A. Explain that every measure will be taken to provide his wife with the best care possible.
- B. Explain that the nurse is fully trained and has years of experience.
- C. Offer the husband a place to relax.
- D. Have appropriate staff discuss his health insurance with him.
Correct Answer: A
Rationale: The correct answer is A because it addresses the husband's concern directly by assuring him that every measure will be taken to provide the best care for his wife. This response shows empathy and provides reassurance, which is crucial in such a stressful situation. It helps to alleviate the husband's anxiety and fear by emphasizing the hospital's commitment to his wife's well-being.
Explanation for why the other choices are incorrect:
B: This response does not address the husband's immediate concern about his wife's well-being and may come across as dismissive.
C: Offering a place to relax does not address the husband's specific question and does not provide the information he is seeking.
D: Discussing health insurance is not appropriate at this moment of crisis and does not address the husband's fears about his wife's condition.
The nurse is caring for a patient who has a temporary percutaneous dialysis catheter in place. In caring for this patient, the nurse should
- A. apply a sterile gauze dressing to maintain sterility.
- B. replace the transparent dressing every 10 days to prevent manipulation.
- C. assess the catheter site for redness and/or swelling.
- D. use the catheter for drawing blood samples to reduce patient discomfort.
Correct Answer: C
Rationale: The correct answer is C because assessing the catheter site for redness and/or swelling is crucial for early detection of infection. Redness and swelling are common signs of infection at the catheter site, which requires prompt intervention. Applying a sterile gauze dressing (choice A) is not necessary for a temporary percutaneous dialysis catheter. Replacing the transparent dressing every 10 days (choice B) is not recommended as it can increase the risk of infection. Using the catheter for drawing blood samples (choice D) is not appropriate as it can introduce contaminants and increase the risk of infection. Regular assessment of the catheter site is essential for early detection and prevention of complications.
A client with asthma receives a prescription for high blood pressure during a clinic visit. Which prescription should the nurse anticipate the client to receive that is least likely to exacerbate asthma?
- A. Carteolol (Ocupress)
- B. Propranolol hydrochloride (Inderal)
- C. Pindolol (Visken)
- D. Metoprolol tartrate (Lopressor)
Correct Answer: D
Rationale: The correct answer is D, Metoprolol tartrate (Lopressor). Metoprolol is a cardioselective beta-blocker that primarily targets beta-1 receptors in the heart, making it less likely to exacerbate asthma compared to non-selective beta-blockers like Propranolol (choice B) and Pindolol (choice C). Carteolol (choice A) is also a non-selective beta-blocker and can potentially worsen asthma symptoms. Metoprolol's selectivity for beta-1 receptors minimizes bronchoconstriction, making it the safest choice for a client with asthma and high blood pressure.
The nurse is caring for a mechanically ventilated patient following bilateral lung transplantation. When planning the care of this patient, what is the priority nursing intervention?
- A. Thirty-degree elevation of head of bed
- B. Endotracheal suctioning as needed
- C. Frequent side to side repositioning
- D. Sequential compression stockings
Correct Answer: A
Rationale: The correct answer is A: Thirty-degree elevation of the head of the bed. This is the priority nursing intervention for a mechanically ventilated patient following bilateral lung transplantation because it helps optimize ventilation-perfusion matching, reduces the risk of aspiration, and improves oxygenation. Elevating the head of the bed also decreases the risk of ventilator-associated pneumonia.
B: Endotracheal suctioning as needed is important but not the priority intervention in this case.
C: Frequent side to side repositioning is important for preventing pressure ulcers but is not the priority for a ventilated patient post-lung transplant.
D: Sequential compression stockings are used for preventing deep vein thrombosis, which is important but not the priority in this scenario.
The nurse is preparing to obtain a pulmonary artery occlusion pressure (PAOP) reading for a patient who is mechanically ventilated. Ensuring that the aaibri-rbf.lcuoimd/ teinstt erface is at the level of the phlebostatic axis, what is the best nursing action?
- A. Place the patient in the supine position and record the PAOP immediately after exhalation.
- B. Place the patient in the supine position and document the average PAOP obtained after three measurements.
- C. Place the patient with the head of bed elevated 30 degrees and document the average PAOP pressure obtained.
- D. Place the patient with the head of bed elevated 30 degr ees and record the PAOP just before the increase in pressures during inhalation.
Correct Answer: C
Rationale: The correct answer is C because placing the patient with the head of the bed elevated 30 degrees is the best position for obtaining an accurate PAOP reading. Elevating the head of the bed helps to align the phlebostatic axis with the atrium, ensuring an accurate measurement of PAOP. This position reduces the impact of hydrostatic pressure on the reading. Options A and D are incorrect because the supine position and recording during exhalation or just before the increase in pressures during inhalation can lead to inaccurate readings. Option B is incorrect because documenting the average PAOP after three measurements does not address the importance of positioning for accuracy.
