Question 1 of 9

The patient is receiving neuromuscular blockade. Which nursing assessment indicates a target level of paralysis?

Correct Answer: B

Rationale: The correct answer is B: Train-of-four yields two twitches. This assessment indicates a target level of paralysis because a train-of-four ratio of 2 twitches out of 4 suggests a 50% neuromuscular blockade, which is often the goal for patients receiving paralysis for procedures or ventilation. A: A Glasgow Coma Scale score of 3 assesses consciousness, not neuromuscular blockade. C: A Bispectral index of 60 measures depth of anesthesia, not paralysis level. D: CAM-ICU assesses delirium, not neuromuscular blockade.

Question 2 of 9

Which therapeutic interventions may be withdrawn or withabhirebl.dco mfr/otemst the terminally ill client? (Select all that apply.)

Correct Answer: B

Rationale: The correct answer is B: Dialysis. In the context of terminally ill clients, withdrawing dialysis is appropriate as it can be burdensome without providing significant benefit towards the end of life. Dialysis does not cure terminal conditions and can prolong suffering unnecessarily. Antibiotics (A) may be necessary for managing infections in terminally ill clients. Nutrition (C) is important for comfort and quality of life. Pain medications (D) are essential for managing pain and should not be withdrawn unless no longer beneficial or requested by the patient.

Question 3 of 9

The family of a critically ill patient has asked to discuss organ donation with the patient’s nurse. When preparing to answer the family’s questions, th e nurse understands which concern(s) most often influence a family’s decision to donate? (Select all that apply.)

Correct Answer: A

Rationale: Rationale for Correct Answer A: Donor disfigurement influences on funeral care. Families often consider the impact of organ donation on the appearance of their loved one during funeral arrangements. This concern can significantly influence their decision to donate. Incorrect Answers: B: Fear of inferior medical care provided to donor. This is not a common concern as medical care for donors is typically of high quality. C: Age and location of all possible organ recipients. While important, this is not a primary concern for families when deciding on organ donation. D: Concern that donated organs will not be used. Families are generally more concerned about the impact on their loved one's appearance post-donation rather than the utilization of organs.

Question 4 of 9

The nurse is caring for a patient receiving peritoneal dialysis. The patient suddenly complains of abdominal pain and chills. The patient’s temperature is elevated. The nurse should

Correct Answer: D

Rationale: Step 1: Abdominal pain, chills, and elevated temperature suggest a serious complication like visceral perforation. Step 2: Peritoneal dialysate return assessment won't address the potential life-threatening issue. Step 3: Checking blood sugar or evaluating neurological status is not relevant to the presenting symptoms. Step 4: Informing the provider of probable visceral perforation is crucial for prompt intervention and further evaluation.

Question 5 of 9

The nurse is caring for a patient with a subarachnoid hemorrhage who is intubated and placed on a mechanical ventilator with 10 cm H2O of peak end-expiratory pressure (PEEP). When monitoring the patient, the nurse will need to notify the healthcare provider immediately if the patient develops:

Correct Answer: D

Rationale: The correct answer is D: Increased jugular venous distention. In a patient with a subarachnoid hemorrhage and on mechanical ventilation, increased jugular venous distention can indicate increased intracranial pressure, which can be life-threatening. The nurse should notify the healthcare provider immediately as it may require urgent intervention to prevent further neurological deterioration. A: Oxygen saturation of 93% is within the acceptable range for a patient on mechanical ventilation and may not require immediate notification. B: Respirations of 20 breaths/minute are within normal limits for a ventilated patient and do not necessarily indicate a critical condition. C: Green nasogastric tube drainage may indicate the presence of bile and could be related to gastrointestinal issues, but it does not pose an immediate threat to the patient's neurological status.

Question 6 of 9

When performing an initial pulmonary artery occlusion pr essure (PAOP), what are the best nursing actions? (Select all that apply.)

Correct Answer: A

Rationale: The correct answer is A: Inflate the balloon for no more than 8 to 10 seconds while noting the waveform change. This is because inflating the balloon within this time frame allows for accurate measurement of PAOP without causing complications like pulmonary edema. Noting the waveform change helps in determining the accurate pressure reading. Explanation of why other choices are incorrect: B: Inflating the balloon with air and recording the volume necessary is not a recommended practice as it can lead to inaccurate readings and potential harm to the patient. C: Maintaining the balloon inflated for 8 hours following insertion is unnecessary and could lead to complications such as vascular damage or thrombosis. D: Zero referencing and leveling the transducer at the phlebostatic axis are important steps but not directly related to performing an initial PAOP measurement.

Question 7 of 9

The nurse returns from the cardiac catheterization laboratory with a patient following insertion of a pulmonary artery catheter and assists in transferring th e patient from the stretcher to the bed. Prior to obtaining a cardiac output, which action is m ost important for the nurse to complete?

Correct Answer: B

Rationale: The correct answer is B: Zero reference the transducer system at the phlebostatic axis. This is the most important action before obtaining a cardiac output because zero referencing ensures accurate pressure readings. The phlebostatic axis is the level of the atria when the patient is supine, and zeroing at this point minimizes errors in pressure measurements. Choice A is incorrect because documenting a pulmonary artery catheter occlusion pressure is not the priority at this stage. Choice C is incorrect as inflating the balloon with air should be done after zero referencing. Choice D is incorrect as injecting normal saline into the port is not necessary before zero referencing.

Question 8 of 9

The patient has just returned from having an arteriovenous fistula placed. The patient asks, “When will they be able to use this and take this other catheter out?” The nurse should reply,

Correct Answer: C

Rationale: The correct answer is C: “The fistula will be usable in about 4 to 6 weeks.” The rationale for this is that an arteriovenous fistula typically requires 4 to 6 weeks to mature and be ready for use. During this time, the fistula develops the necessary blood flow for efficient dialysis. Choice A is incorrect because immediate use of the fistula is not recommended as it needs time to mature. Choice B is incorrect as it underestimates the time needed for the fistula to heal and mature. Choice D is incorrect as the usability of the fistula is not dependent on the manufacturer but rather on the patient's individual healing process.

Question 9 of 9

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?

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.
