Exam Cram NCLEX RN Practice Questions

1. Which of these findings indicate that a pump to deliver a basal rate of 10 ml per hour plus PRN for pain breakthrough for a morphine drip is not working?

A. The client complains of discomfort at the IV insertion site
B. The client states 'I just can't get relief from my pain.'
C. The level of the drug is 100 ml at 8 AM and is 80 ml at noon
D. The level of the drug is 100 ml at 8 AM and is 50 ml at noon

Correct answer: C

Rationale: The correct answer is that the level of the drug is 100 ml at 8 AM and is 80 ml at noon. With a basal rate of 10 mL per hour, a total of 40 mL should have been infused by noon, leaving only 60 mL in the container. Any amount greater than 60 mL at noon indicates that the pump is not functioning properly. Therefore, the finding of 80 mL at noon suggests the pump is not delivering the expected medication volume. Choices A and B are related to the client's symptoms and may indicate the need for pain management assessment but do not specifically indicate pump malfunction. Choice D, where the level drops to 50 mL at noon, would actually indicate that the pump is working effectively, as the expected volume has been delivered.

2. While eating in the hospital cafeteria, a nurse notices a toddler at a nearby table choking on a piece of food and appearing slightly blue. What is the appropriate initial action to take?

A. Begin mouth-to-mouth resuscitation
B. Give the child water to help with swallowing
C. Perform 5 abdominal thrusts
D. Call for the emergency response team

Correct answer: C

Rationale: When a toddler is choking on a piece of food and appears blue, it indicates airway obstruction. The appropriate initial action should be to perform 5 abdominal thrusts. This technique can help dislodge the obstructing object and clear the airway. Initiating mouth-to-mouth resuscitation is not recommended as the first step in a choking emergency, especially in children. Giving water may not be effective and can worsen the situation by causing further blockage. Calling the emergency response team should be considered if the abdominal thrusts are unsuccessful in clearing the airway.

3. Which of the following can cause coup-contrecoup injuries?

A. Rotational forces
B. Deformation forces
C. Deceleration forces
D. Acceleration forces

Correct answer: C

Rationale: Deceleration forces occur when the head is moving and abruptly comes to a stop, such as in a car crash. This sudden deceleration can cause the brain to hit against the skull, resulting in coup-contrecoup injuries. In a coup-contrecoup injury, the brain is damaged on opposite sides due to the initial impact and the rebound effect inside the skull. Rotational forces usually result in diffuse axonal injuries rather than coup-contrecoup injuries. Deformation forces can cause focal brain injuries but not coup-contrecoup injuries. Acceleration forces typically lead to diffuse brain injuries, not coup-contrecoup injuries. Therefore, the correct answer is deceleration forces.

4. Which entry in the medical record best meets the requirement for problem-oriented charting?

A. "A: Pacing and muttering to self. P: Sensory perceptual alteration, related to internal auditory stimulation. I: Given fluphenazine (Prolixin) 2.5 mg at 0900, and went to room to lie down. E: Calmer by 0930. Returned to lounge to watch TV."?
B. "S: States, 'I feel like I'm ready to blow up.' O: Pacing hall, mumbling to self. A: Auditory hallucinations. P: Offer haloperidol (Haldol) 2 mg . I: (Haldol) 2 mg at 0900. E: Returned to lounge at 0930 and quietly watched TV."?
C. "Agitated behavior. D: Patient muttering to self as though answering an unseen person. A: Given haloperidol (Haldol) 2 mg and went to room to lie down. E: Patient calmer. Returned to lounge to watch TV."?
D. "Pacing hall and muttering to self as though answering an unseen person. haloperidol (Haldol) 2 mg administered at 0900 with calming effect in 30 minutes. Stated, 'I'm no longer bothered by the voices.'"?

Correct answer: B

Rationale: Problem-oriented documentation uses the first letter of key words to organize data: S for subjective data, O for objective data, A for assessment, P for plan, I for intervention, and E for evaluation. The correct answer demonstrates problem-oriented charting by following this structure. Choice A, C, and D do not follow the problem-oriented charting format and instead offer examples of different documentation styles such as PIE charting, focus documentation, and narrative documentation, respectively. Therefore, choice B is the best example of problem-oriented charting among the options provided.

5. Septic, anaphylactic, and neurogenic shock are all categorized as:

A. Hypovolemic shock
B. Cardiogenic shock
C. Distributive shock
D. Obstructive shock

Correct answer: C

Rationale: Septic, anaphylactic, and neurogenic shock are all types of distributive shock. Distributive shock is characterized by a decrease in systemic vascular resistance, leading to poor tissue perfusion. Septic shock is caused by severe infection, anaphylactic shock is an extreme allergic reaction, and neurogenic shock results from damage to the nervous system. Hypovolemic shock (Choice A) is characterized by a decrease in intravascular volume, cardiogenic shock (Choice B) is due to heart failure, and obstructive shock (Choice D) results from obstruction of blood flow. Therefore, the correct categorization for septic, anaphylactic, and neurogenic shock is distributive shock.
