NCLEX RN Exam Preview Answers
1. When is the best time for the nurse to attempt to elicit the Moro reflex during an infant examination?
- A. When the infant is sleeping
- B. At the end of the examination
- C. Before auscultation of the thorax
- D. At about the middle of the examination
Correct answer: B
Rationale: The Moro reflex, also known as the startle reflex, is best elicited at the end of the examination because it can cause the infant to cry. This reflex is triggered by a sudden change in position or loud noise, and it involves the infant's arms extending and then coming back together as if embracing. By eliciting this reflex at the end of the examination, the nurse can observe the infant's response and ensure that the examination is completed without unnecessary distress. Choices A, C, and D are incorrect because the Moro reflex is typically elicited at the end of the examination to avoid disrupting the assessment process and causing unnecessary discomfort to the infant.
2. What is the initial step to take when a patient passes out at the front desk?
- A. Call 911.
- B. Initiate CPR.
- C. Shake the patient and ask if they are okay.
- D. Check for a pulse.
Correct answer: C
Rationale: The correct initial step when a patient passes out at the front desk is to shake the patient gently and ask if they are okay. This step aims to assess the patient's level of responsiveness. Checking for a pulse or initiating CPR should only be done if the patient does not respond to being shaken. Calling 911 can be the next step after assessing the patient's immediate condition and providing necessary assistance.
3. A client is preparing to irrigate a colostomy. Which of the following situations is a contraindication for this type of irrigation?
- A. The client has an incontinent ostomy
- B. The client has an irregular bowel routine
- C. The client has diverticulitis
- D. The colostomy bag contains fecal material
Correct answer: C
Rationale: When a client with a colostomy is preparing for irrigation, it is essential to consider contraindications that could pose risks or worsen the client's condition. Diverticulitis is a contraindication for colostomy irrigation because the inflamed diverticula could be further irritated by the flushing action during irrigation, potentially leading to complications. An incontinent ostomy, irregular bowel routine, or presence of fecal material in the colostomy bag are not specific contraindications for irrigation and can be managed through appropriate techniques and interventions.
4. When considering the structural organization of the human body, what is the basic unit of life?
- A. Chemicals
- B. Atoms
- C. Molecules
- D. Cells
Correct answer: D
Rationale: The basic unit of life is the cell. Cells are considered the fundamental unit of life because they are capable of carrying out all the processes necessary for life, such as growth, reproduction, responding to stimuli, and more. While chemicals, atoms, and molecules are essential components of cells and living organisms, they are not considered the basic unit of life. Chemicals are general substances, atoms are the smallest units of matter, and molecules are combinations of atoms. Therefore, the correct answer is cells, as they are the building blocks of all living organisms.
5. A leukemia patient has a relative who wants to donate blood for transfusion. Which of the following donor medical conditions would prevent this?
- A. A history of hepatitis C five years previously
- B. Cholecystitis requiring cholecystectomy one year previously
- C. Asymptomatic diverticulosis
- D. Crohn's disease in remission
Correct answer: A
Rationale: A history of hepatitis C five years previously would prevent a donor from donating blood for transfusion. Hepatitis C is a viral infection transmitted through bodily fluids, such as blood, causing inflammation of the liver. Patients with hepatitis C may not donate blood for transfusion due to the high risk of infection in the recipient. Cholecystitis requiring cholecystectomy one year previously, asymptomatic diverticulosis, and Crohn's disease in remission are not contraindications for blood donation as they do not pose a risk of transmitting infections to the recipient.
