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.

Which nursing actions are most important for a patient witahb irab .croigmh/tte srta dial arterial line? (Select all that apply.)
- A. Checking the circulation to the right hand every 2 hour s
- B. Maintaining a pressurized flush solution to the arterial line setup
- C. Monitoring the waveform on the monitor for dampenin g
- D. Restraining all four extremities with soft limb restraint s
Correct Answer: A
Rationale: Step 1: Checking circulation to the right hand is crucial for assessing perfusion and detecting potential complications.
Step 2: Arterial line placement can compromise blood flow, leading to ischemia if circulation is impaired.
Step 3: Monitoring circulation every 2 hours allows for early detection of issues and prompt intervention.
Step 4: This action ensures patient safety and prevents complications.
Summary:
- Choice B is incorrect as pressurized flush solution can increase the risk of complications.
- Choice C is incorrect as monitoring the waveform is important but not the most critical action.
- Choice D is incorrect as limb restraints can impede circulation and are unnecessary in this scenario.
When rewarming a patient who arrived in the emergency department (ED) with a temperature of 87°F (30.6°C), which assessment indicates that the nurse should discontinue active rewarming?
- A. The patient begins to shiver.
- B. The BP decreases to 86/42 mm Hg.
- C. The patient develops atrial fibrillation.
- D. The core temperature is 94°F (34.4°C).
Correct Answer: D
Rationale: The correct answer is D. When rewarming a hypothermic patient, the goal is to gradually increase their core temperature. A core temperature of 94°F (34.4°C) is still below the normal range, but it indicates that the rewarming process is working. Shivering (A) is a normal response to rewarming. A decrease in blood pressure (B) may be expected due to peripheral vasodilation during rewarming. Developing atrial fibrillation (C) may be a concern but does not necessarily indicate that rewarming should be discontinued. Therefore, choice D is correct as it signifies progress in the rewarming process.
The nurse is assessing a client who complains of weight loss, racing heart rate, and difficulty sleeping. The nurse determines the client has moist skin with fine hair, prominent eyes, lid retraction, and a staring expression. These findings are consistent with which disorder?
- A. Grave's disease.
- B. Multiple sclerosis.
- C. Addison's disease.
- D. Cushing syndrome.
Correct Answer: A
Rationale: Step 1: Symptoms of weight loss, racing heart rate, and difficulty sleeping are common in hyperthyroidism.
Step 2: Presence of moist skin, fine hair, prominent eyes, lid retraction, and staring expression are classic signs of Grave's disease, a type of hyperthyroidism.
Step 3: Grave's disease is an autoimmune disorder where the thyroid gland is overactive, leading to excessive production of thyroid hormones.
Step 4: Excess thyroid hormones increase metabolic rate, causing weight loss, racing heart rate, and insomnia.
Step 5: Therefore, the findings described in the question are consistent with Grave's disease.
After the change-of-shift report, which patient should the progressive care nurse assess first?
- A. Patient who was extubated in the morning and has a temperature of 101.4°F (38.6°C).
- B. Patient with bilevel positive airway pressure (BiPAP) for sleep apnea whose respiratory rate is 16.
- C. Patient with arterial pressure monitoring who is 2 hours post percutaneous coronary intervention and needs to void.
- D. Patient who is receiving IV heparin for venous thromboembolism and has a partial thromboplastin time (PTT) of 98 seconds.
Correct Answer: D
Rationale: The correct answer is D. The patient receiving IV heparin with a PTT of 98 seconds is at risk for bleeding due to the therapeutic range of 60-80 seconds. Assessing this patient first is crucial to prevent potential bleeding complications. A high PTT indicates the blood is not clotting properly, increasing the risk of bleeding. Prompt assessment and possible adjustment of heparin infusion are needed.
A: The patient with a temperature of 101.4°F may have a fever but is not at immediate risk compared to the patient with a high PTT.
B: The patient on BiPAP with a respiratory rate of 16 is stable and does not require immediate assessment.
C: The patient post-percutaneous coronary intervention needing to void is a routine need and does not require immediate attention compared to the patient with a critical lab value.
Which action is a priority for the nurse to take when the low-pressure alarm sounds for a patient who has an arterial line in the left radial artery?
- A. Fast flush of the arterial line.
- B. Check the left hand for pallor.
- C. Assess for cardiac dysrhythmias.
- D. Rezero the monitoring equipment.
Correct Answer: C
Rationale: Rationale for Correct Answer (C): When the low-pressure alarm sounds for a patient with an arterial line, the nurse should assess for cardiac dysrhythmias first. This is because a sudden drop in pressure could indicate a serious issue affecting the heart's ability to pump effectively. Identifying and addressing any cardiac dysrhythmias promptly is crucial for patient safety.
Summary of Incorrect Choices:
A: Fast flush of the arterial line - This would not address the underlying cause of the low-pressure alarm and may not be necessary.
B: Check the left hand for pallor - While assessing perfusion is important, it is not the priority when the alarm indicates a potential cardiac issue.
D: Rezero the monitoring equipment - While important for accuracy, it is not the priority when the alarm indicates a potential cardiac concern.
