NCLEX RN Predictor Exam

1. When are manual hematocrits done?

A. to monitor anemia
B. by using a microhematocrit tube.
C. to measure the percentage of plasma to cells.
D. All of the above.

Correct answer: D

Rationale: Manual hematocrits are performed to monitor anemia, which involves measuring the percentage of red blood cells in the blood. The process involves collecting blood in a microhematocrit tube, then centrifuging it to separate the plasma from the cells. By measuring the ratio of plasma to cells, healthcare providers can assess the patient's hematocrit level. Therefore, all the provided options are correct as they collectively describe the purpose and procedure of manual hematocrits.

2. Which of the following constitutes the five rights of medication administration?

A. Right client, right nurse, right time, right dose, right route
B. Right client, right time, right dose, right route, right order
C. Right client, right drug, right dose, right time, right route
D. Right physician, right nurse, right client, right drug, right dose

Correct answer: C

Rationale: The five rights of medication administration are essential to ensure safe and effective drug delivery to clients. The correct answer includes ensuring the right client receives the right drug at the right dose, via the right route, and at the right time. These elements are crucial to prevent medication errors and ensure optimal therapeutic outcomes. Choice A is incorrect as it includes 'right nurse' which is not part of the five rights of medication administration. Choice B is incorrect as it includes 'right order' which is not part of the five rights. Choice C is incorrect as it includes 'right drug' and 'right route', but it lacks 'right client' and 'right time'. Choice D is incorrect as it includes 'right physician' which is not part of the five rights.

3. All of the following factors may contribute to client falls EXCEPT:

A. Contact dermatitis
B. Urinary frequency
C. Decreased visual acuity
D. Confusion

Correct answer: A

Rationale: Client falls can result from various factors, both intrinsic and extrinsic. Intrinsic factors include health conditions like urinary frequency, which increases the need for bathroom visits, decreased visual acuity, and confusion. These factors can directly contribute to an increased risk of falls. However, contact dermatitis does not directly lead to falls. Contact dermatitis is a skin condition caused by contact with irritants or allergens and does not inherently predispose individuals to falling. Therefore, among the given options, contact dermatitis is the only factor that is not directly associated with an increased risk of falls.

4. A 30-year-old woman has recently moved to the United States with her husband. They are living with the woman's sister until they can get a home of their own. When company arrives to visit the woman's sister, the woman feels suddenly shy and retreats to the back bedroom to hide until the company leaves. She explains that her reaction to guests is simply because she does not know how to speak "perfect English."? What is this woman likely experiencing?

A. Culture shock
B. Cultural taboos
C. Cultural unfamiliarity
D. Culture disorientation

Correct answer: A

Rationale: The woman in the scenario is likely experiencing culture shock. Culture shock is a term used to describe the state of disorientation or inability to respond to the behavior of a different cultural group due to sudden strangeness, unfamiliarity, and incompatibility with the individual's perceptions and expectations. In this case, the woman's feelings of shyness and retreating due to not feeling confident in speaking 'perfect English' align with symptoms of culture shock. The other choices are incorrect: Cultural taboos refer to behaviors or actions that are prohibited within a particular culture; cultural unfamiliarity suggests a lack of knowledge about a specific culture, which is not the case here; and culture disorientation is not a commonly used term in cultural psychology, making it an incorrect option.

5. A client is having difficulties reading an educational pamphlet. He cannot find his glasses. In order to read the words, he must hold the pamphlet at arm's length, which allows him to read the information. Which vision deficit does this client most likely suffer from?

A. Cataracts
B. Glaucoma
C. Astigmatism
D. Presbyopia

Correct answer: D

Rationale: Presbyopia is a condition that occurs when the lens of the eye loses accommodation and is unable to focus light on objects nearby. As a result, clients are unable to see or read items up close but may have success when holding the same item at arm's length. Many clients with presbyopia must wear bifocals, but long-distance vision remains unaffected. Cataracts involve clouding of the eye's lens, leading to blurry vision. Glaucoma is associated with increased intraocular pressure that damages the optic nerve, causing vision loss. Astigmatism is a refractive error where the cornea or lens has an irregular shape, leading to distorted or blurred vision.
