manual hematocrits are done

NCLEX-RN

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. When providing culturally competent care, nurses must incorporate cultural assessments into their health assessments. Which statement is most appropriate to use when initiating an assessment of cultural beliefs with an older American Indian patient?

A. "Are you of the Christian faith?"?
B. "Do you want to see a medicine man?"?
C. "How often do you seek help from medical providers?"?
D. "What cultural or spiritual beliefs are important to you?"?

Correct answer: D

Rationale: The nurse needs to assess the cultural beliefs and practices of the patient and should ask questions in a way that communicates acceptance of their beliefs and allows for open communication. Therefore, the most appropriate question to initiate an assessment of cultural beliefs with an older American Indian patient is "What cultural or spiritual beliefs are important to you?"? This question shows respect for the patient's beliefs and encourages them to share relevant information. Asking if they are of the Christian faith does not promote open communication and may not reflect the patient's actual beliefs. While some American Indians may seek assistance from a medicine man or shaman, it is not appropriate to make assumptions without direct input from the patient. Asking how often they seek help from medical providers is not directly related to understanding their cultural beliefs and may not provide relevant insights for culturally competent care.

3. Intermittent fevers are:

A. fevers which come and go.
B. fevers which rise and fall but are always considered above the patient's average temperature.
C. fevers which fluctuate more than three degrees and never return to normal.
D. None of the above.

Correct answer: A

Rationale: Intermittent fevers are characterized by periods of fever followed by periods of normal body temperature. They alternate between being febrile and afebrile. Continuous fevers show minimal fluctuations over a 24-hour period, while remittent fevers fluctuate significantly but do return to normal body temperature. Choice A is correct as it accurately describes intermittent fevers. Choices B and C are incorrect as they do not fully capture the defining characteristic of intermittent fevers, which involve cyclical episodes of fever and normal temperature. Choice D is incorrect as there is a specific definition for intermittent fevers.

4. A client is diagnosed with ariboflavinosis. Which of the following foods should the nurse serve this client?

A. Citrus fruits
B. Milk
C. Fish
D. Potatoes

Correct answer: B

Rationale: Ariboflavinosis is a vitamin B-2 deficiency. Symptoms may include cracks around the mouth, inflammation of the tongue, or light sensitivity. Foods rich in vitamin B-2, like milk, liver, green vegetables, or whole grains, are recommended. Citrus fruits (choice A) are good sources of vitamin C, not B-2. Fish (choice C) is a source of protein and omega-3 fatty acids but not a significant source of vitamin B-2. Potatoes (choice D) are a source of carbohydrates but do not provide high levels of vitamin B-2.

5. A client is being assisted with ambulation in the hallway using a gait belt when they become dizzy and start to faint. What is the first action the nurse should take?

A. Stand behind the client and prepare to catch them if they fall
B. Assist the client to sit in the nearest chair or slide down along a wall
C. Grasp the client under the arms and pull them upward
D. Call for help from nearby staff

Correct answer: A

Rationale: If a client becomes dizzy and starts to faint while being assisted with ambulation, the nurse's first action should be to assist the client into a sitting position to prevent or reduce the impact of a fall. This can be done by guiding the client to sit in the nearest chair or sliding down along a wall for support. Option A is incorrect because standing behind the client may not prevent a fall and could potentially lead to injury. Option C is incorrect as pulling the client upward may worsen the situation. Option D, calling for help, is not the first action to take when the client is at risk of falling.
