NCLEX RN Predictor Exam

1. Each small square on the EKG paper is:

A. 0.04 seconds long and 5mm tall
B. 0.2 seconds long and 5mm tall
C. 0.04 seconds long and 20mm tall
D. 0.04 seconds long and 1mm tall

Correct answer: D

Rationale: Each small square on an EKG paper represents 0.04 seconds long and 1mm tall. This standardization is essential for accurate measurements. One large square on EKG paper consists of 5 small squares in length and 5 small squares in height, which equals 0.2 seconds long and 5mm tall (0.5 mV). Choice A is incorrect because while the duration is correct, the height mentioned is not accurate. Choice B is incorrect as it provides the correct height but the duration is inaccurate. Choice C is incorrect as the height mentioned is exaggerated, and the duration is correct but the height is not. Therefore, the correct answer is 0.04 seconds long and 1mm tall.

2. In the term 'Hemoglobin,' the suffix '-globin' means:

A. Protein
B. Iron
C. Metal
D. Blood

Correct answer: A

Rationale: The suffix '-globin' in the term 'Hemoglobin' specifically refers to a protein. Hemoglobin is a protein found in red blood cells that carries oxygen. Choice B, 'Iron,' is incorrect as iron is a mineral component of hemoglobin but not the meaning of the suffix. Choice C, 'Metal,' is too broad and not specific to the meaning of the suffix in this context. Choice D, 'Blood,' is incorrect as it refers to the overall term 'Hemoglobin' rather than the specific meaning of the suffix '-globin.' Therefore, the correct answer is A: 'Protein.'

3. A registered nurse who usually works in a spinal rehabilitation unit is floated to the emergency department. Which of these clients should the charge nurse assign to this RN?

A. A middle-aged client who says, "I took too many diet pills"? and "my heart feels like it is racing out of my chest."?
B. A young adult who says, "I hear songs from heaven. I need money for beer. I quit drinking two (2) days ago for my family. Why are my arms and legs jerking?"?
C. An adolescent who has been on pain medications for terminal cancer with an initial assessment finding of pinpoint pupils and a relaxed respiratory rate of 11.
D. An elderly client who reports having taken a "large crack hit"? 10 minutes prior to walking into the emergency room.

Correct answer: C

Rationale: When assigning a floated nurse from another unit to a client in the emergency department, the goal is to choose a patient with minimal anticipated immediate complications. In this scenario, the adolescent with terminal cancer who has been on pain medications and presents with pinpoint pupils and a relaxed respiratory rate of 11 is the most stable option. These assessment findings indicate opioid toxicity, which, while serious, has the least risk of immediate complications compared to the other clients. Choice A involves a middle-aged client experiencing symptoms of possible cardiac issues due to diet pill overdose, which requires urgent intervention. Choice B presents a young adult with concerning symptoms of potential psychosis or substance withdrawal, requiring immediate attention. Choice D involves an elderly client who recently used crack, posing a high-risk situation that requires prompt evaluation and intervention. Therefore, the correct choice is the adolescent with opioid toxicity, as this client has the least immediate risk of complications among the options provided.

4. Which of the following lists the recommended sequence for removing soiled personal protective equipment when preparing to leave a patient's room?

A. Gown, goggles, mask, gloves, and exit the room.
B. Gloves, wash hands, remove gown, mask, and goggles.
C. Gloves, goggles, gown, mask, and wash hands.
D. Gloves, goggles, gown, mask, and wash hands.

Correct answer: D

Rationale: The correct sequence for removing soiled personal protective equipment is crucial to prevent contamination. Gloves should always be removed first as they are most likely to be contaminated. Following the removal of gloves, goggles, gown, mask, and finally washing hands is recommended. Choice A is incorrect as gloves should be removed first. Choice B is incorrect as the sequence is not in the recommended order. Choice D is incorrect as gloves should be removed before goggles.

5. The nurse is comparing the concepts of religion and spirituality. Which statement describes an appropriate component of one's spirituality?

A. Belief in and worship of God or gods
B. Being closely tied to one's ethnic background
C. Attendance at a specific church or place of worship
D. A connection with something larger than oneself and belief in transcendence

Correct answer: D

Rationale: Spirituality refers to a connection with something larger than oneself and a belief in transcendence. The other responses do not apply to spirituality. Choice A, 'Belief in and worship of God or gods,' and choice C, 'Attendance at a specific church or place of worship,' are more aligned with religious practices. Choice B, 'Being closely tied to one's ethnic background,' is not a defining aspect of spirituality or religion as it pertains more to cultural identity rather than spiritual beliefs.
