Exam Cram NCLEX RN Practice Questions

1. Which of the following is TRUE about shock?

A. A patient with severe shock does not always have an abnormally low blood pressure.
B. Confusion and deteriorating mentation are indicative of hypotensive shock.
C. Patients with compensated shock may not be able to maintain a normal blood pressure.
D. A normal blood pressure does not imply that the patient is stable.

Correct answer: B

Rationale: Confusion and deteriorating mentation are indeed indicative of hypotensive shock. It is important to note that a patient with hypotensive shock will likely exhibit deteriorating mental status. Choice A is incorrect because a patient in severe shock may not always have an abnormally low blood pressure, making it an unreliable indicator of shock severity. Choice C is incorrect because patients with compensated shock may present with normal blood pressure but still have inadequate tissue perfusion. Choice D is incorrect because a normal blood pressure does not guarantee the patient's stability, especially in cases of shock where tissue perfusion may be compromised despite normal blood pressure readings.

2. Using the illustrated technique, the healthcare provider is assessing for which finding in a patient with chronic obstructive pulmonary disease (COPD)?

A. Hyperresonance
B. Tripod positioning
C. Accessory muscle use
D. Reduced chest expansion

Correct answer: D

Rationale: The technique for palpation for chest expansion is shown in the illustrated technique. Reduced chest expansion would be noted on palpation of a patient's chest with COPD. Hyperresonance would be assessed through percussion, not palpation. Accessory muscle use and tripod positioning would be assessed by inspection, not palpation.

3. A nurse frequently treats patients in the 72-hour period after a stroke has occurred. The nurse would be most concerned about which of these assessment findings?

A. INR is 3 seconds long
B. Heart rate is 110 beats per minute
C. Intracranial Pressure is 22 mmHg
D. Blood pressure is 140/80

Correct answer: C

Rationale: The nurse would be most concerned about the assessment finding of an Intracranial Pressure (ICP) reading of 22 mmHg in a patient 72 hours post-stroke. Elevated ICP can indicate increased risk of edema and further brain damage. A target ICP should ideally be maintained at less than or equal to 15-20 mmHg. While the other options may also be important to monitor, an elevated ICP poses a more immediate threat to the patient's neurological status and requires prompt attention.

4. A patient in metabolic alkalosis is admitted to the emergency department, and pulse oximetry indicates that the O2 saturation is 94%. Which action should the nurse take next?

A. Administer bicarbonate.
B. Complete a head-to-toe assessment.
C. Place the patient on high-flow oxygen.
D. Obtain repeat arterial blood gases (ABGs).

Correct answer: C

Rationale: In a patient with metabolic alkalosis and an O2 saturation of 94%, placing the patient on high-flow oxygen is the correct action. Even though the O2 saturation seems adequate, metabolic alkalosis causes a left shift in the oxyhemoglobin dissociation curve, reducing oxygen delivery to tissues. Therefore, providing high-flow oxygen can help compensate for this. Administering bicarbonate would exacerbate the alkalosis. While completing a head-to-toe assessment and obtaining repeat ABGs are important interventions, the priority in this scenario is to improve oxygen delivery by placing the patient on high-flow oxygen.

5. A patient with Glaucoma is verbalizing his daily medication routine to the nurse. He states he has two different eye drop medications, both every twelve hours. He washes his hands, instills the drops, closes his eyes gently, and presses his finger to the corner of his eye nearest his nose. After waiting 1 minute with his eyes closed, he instills the other medication in the same way. What is the nurse's best response?

A. ''You should wait more than 1 minute between different medications.''
B. ''Your routine is very good! Can you demonstrate it for me?''
C. ''It is actually not the best practice to close your eyes after instilling eye drops.''
D. ''You should actually be pressing your finger in the other corner of the eye.''

Correct answer: A

Rationale: It is recommended to wait 10-15 minutes between different eye drop medications to give them time to absorb and avoid one medication washing another one out. Choice A is the correct response as the patient should wait more than 1 minute between administering different eye drop medications. Choice B is incorrect as the routine described by the patient needs improvement. Choice C is inaccurate as closing the eyes after instilling eye drops is a best practice to ensure proper absorption. Choice D is incorrect as pressing the finger to the corner of the eye nearest the nose is the correct technique.
