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. The healthcare professional is preparing to percuss the abdomen of a patient. What characteristic of the underlying tissue does percussion assess?
- A. Turgor
- B. Texture
- C. Density
- D. Consistency
Correct answer: C
Rationale: Percussion is a technique used to assess the density of underlying organs by producing sounds that help determine their location and size. Turgor, texture, and consistency are primarily assessed through palpation, not percussion. Turgor refers to skin elasticity, texture pertains to the feel of the tissue surface, and consistency relates to the firmness or resistance of the tissue.
3. A nurse caring for a client diagnosed with pertussis is ordered to maintain droplet precautions. Which of the following actions of the nurse upholds droplet precautions?
- A. Assign the client to stay in a negative-pressure room
- B. Use sterilized equipment when sharing between this client and another person with pertussis
- C. Wear a mask if coming within 3 feet of the client
- D. Both A and C
Correct answer: C
Rationale: When caring for a client requiring droplet precautions, it is essential for the nurse to wear a mask when within 3 feet of the client. This practice helps prevent the transmission of droplet particles that may be produced when the client coughs or sneezes. Assigning the client to a negative-pressure room is not typically necessary for droplet precautions unless specifically indicated for airborne precautions. Using sterilized equipment when sharing between clients with pertussis is important for infection control but does not directly relate to droplet precautions. Therefore, the correct action to uphold droplet precautions in this scenario is to wear a mask when coming within close proximity to the client.
4. Digestion, elimination, and ___________ are the three functions of the digestive system.
- A. constriction
- B. relaxation
- C. absorption
- D. peristalsis
Correct answer: C
Rationale: The correct answer is 'absorption.' The three main functions of the digestive system are digestion, absorption, and elimination. Absorption refers to the process of absorbing nutrients and other substances from the digested food into the bloodstream. Choices A, B, and D are incorrect: Constriction is not a primary function of the digestive system, relaxation is not a distinct function in this context, and peristalsis is a muscular movement that aids in digestion but is not one of the three main functions of the digestive system.
5. The student observes a patient with no breathing problems. Which action by the student indicates a need to review respiratory assessment skills?
- A. The student starts at the apices of the lungs and moves to the bases.
- B. The student compares breath sounds from side to side, avoiding bony areas.
- C. The student places the stethoscope over the posterior chest and listens during expiration.
- D. The student instructs the patient to breathe slowly and a little more deeply than normal through the mouth.
Correct answer: C
Rationale: The correct answer is C. Listening only during inspiration instead of both inspiration and expiration indicates a need for a review of respiratory assessment skills. During chest auscultation, it is essential to listen to at least one cycle of inspiration and expiration at each placement of the stethoscope. Instructing the patient to breathe slowly and a little deeper than normal through the mouth is a correct practice during auscultation. The correct sequence for lung auscultation is from the apices to the bases, comparing breath sounds bilaterally, avoiding bony areas. It is crucial to place the stethoscope over lung tissue rather than bony prominences to accurately assess lung sounds.
