The nurse is caring for an elderly patient who was admitted with renal insufficiency. An expected laboratory finding for this patient may be
- A. an increased glomerular filtration rate (GFR).
- B. a normal serum creatinine level.
- C. increased ability to excrete drugs.
- D. hypokalemia.
Correct Answer: B
Rationale: The correct answer is B: a normal serum creatinine level. In renal insufficiency, the kidneys are not able to filter waste products effectively, leading to an increase in serum creatinine levels. This is a common indicator of renal dysfunction.
A: An increased GFR would not be expected in renal insufficiency, as it signifies improved kidney function.
C: Increased ability to excrete drugs is not a typical finding in renal insufficiency, as impaired kidney function can lead to drug accumulation.
D: Hypokalemia is not directly related to renal insufficiency. It is more commonly associated with factors like diuretic use or gastrointestinal losses.

The nurse recognizes that which patient is likely to benefit most from patient-controlled analgesia?
- A. 21-year-old with a C4 fracture and quadriplegia
- B. 45-year-old with femur fracture and closed head injury
- C. 59-year-old postoperative elective bariatric surgery
- D. 70-year-old postoperative cardiac surgery; mild demen tia
Correct Answer: A
Rationale: The correct answer is A, the 21-year-old with a C4 fracture and quadriplegia. This patient is likely to benefit most from patient-controlled analgesia (PCA) due to the inability to self-administer traditional pain medications. With quadriplegia, the patient may have limited mobility and sensation, making it challenging to communicate pain levels effectively. PCA allows the patient to control their pain relief within preset limits, enhancing autonomy and optimizing pain management.
Summary:
- Choice B: The 45-year-old with femur fracture and closed head injury may benefit from PCA, but the severity of the head injury could affect their ability to use the device effectively.
- Choice C: The 59-year-old postoperative elective bariatric surgery patient can typically manage pain with traditional methods postoperatively.
- Choice D: The 70-year-old postoperative cardiac surgery patient with mild dementia may have the cognitive ability to use PCA but could potentially benefit more from other pain management strategies due
Following insertion of a pulmonary artery catheter (PAC),a bthirbe. cpohmy/tessitc ian orders the nurse to obtain a blood sample for mixed venous oxygen saturation (SvO ). Which action by the nurse best ensures the obtained value is accurate?
- A. Zero referencing the transducer at the level of the phlebostatic axis following insertion WWWWWW ..TTHHEENNUURRSSIINNGGMMAASSTTEERRYY..CCOOMM
- B. Calibrating the system with a central venous blood sample and arterial blood gas value
- C. Ensuring patency of the catheter using a 0.9% normal asbailrbin.ceo ms/otelsut tion pressurized at 300 mm Hg
- D. Using noncompliant pressure tubing that is no longer t han 36 to 48 inches and has minimal stopcocks
Correct Answer: B
Rationale: The correct answer is B because calibrating the system with central venous and arterial blood samples ensures accuracy of the mixed venous oxygen saturation (SvO2) measurement. This calibration allows for comparison of the values obtained from both sources to confirm the accuracy of the measurement.
Choice A is incorrect because zero referencing the transducer at the level of the phlebostatic axis does not directly address the accuracy of the SvO2 measurement.
Choice C is incorrect because ensuring patency of the catheter using normal saline pressurized at 300 mm Hg does not directly impact the accuracy of the SvO2 measurement.
Choice D is incorrect because using noncompliant pressure tubing does not ensure the accuracy of the SvO2 measurement. The length of the tubing and the presence of stopcocks are not directly related to obtaining an accurate SvO2 value.
The urgent care center protocol for tick bites includes the following actions. Which action will the nurse take first when caring for a patient with a tick bite?
- A. Use tweezers to remove any remaining ticks.
- B. Check the vital signs, including temperature.
- C. Give doxycycline (Vibramycin) 100 mg orally.
- D. Obtain information about recent outdoor activities.
Correct Answer: A
Rationale: The correct answer is A: Use tweezers to remove any remaining ticks. The first step is to remove the tick to prevent further transmission of any potential pathogens. This is crucial in preventing tick-borne illnesses. Checking vital signs (B) can be done after the tick is removed. Administering doxycycline (C) should be based on guidelines and individual factors. Obtaining information about recent outdoor activities (D) is important but not the immediate priority.
The nurse manager is assisting a nurse with improving organizational skills and time management. Which nursing activity is the priority in pre-planning a schedule for selected nursing activities in the daily assignment?
- A. Tracheostomy tube suctioning.
- B. Medication administration.
- C. Colostomy care instruction.
- D. Client personal hygiene.
Correct Answer: B
Rationale: The correct answer is B: Medication administration. This is the priority because medication administration is time-sensitive and crucial for patient safety. It requires precise timing and cannot be delayed. Tracheostomy tube suctioning (A), colostomy care instruction (C), and client personal hygiene (D) are important nursing activities but can be adjusted within the schedule based on patient needs and acuity levels. Prioritizing medication administration ensures that patients receive their medications on time, preventing adverse events and promoting optimal health outcomes.
In calculating the glomerular filtration rate (GFR) results for women, the creatinine clearance is usually:
- A. the same as for men.
- B. greater than that for men.
- C. multiplied by 0.85
- D. multiplied by 1.15.
Correct Answer: C
Rationale: The correct answer is C: multiplied by 0.85. This is because women typically have lower muscle mass compared to men, resulting in lower creatinine production. Therefore, to adjust for this difference, the creatinine clearance for women is multiplied by 0.85. This correction factor helps to more accurately estimate the GFR in women.
Choices A and B are incorrect because the creatinine clearance for women is not the same as or greater than that for men due to the physiological differences in muscle mass. Choice D is also incorrect as multiplying by 1.15 would overestimate the GFR in women.
