Safe and Effective Care Environment NCLEX RN Questions

1. Which of the following may represent an upper airway obstruction?

A. Retractions
B. Elongated expiratory phase
C. Stridor
D. Expiratory wheezing

Correct answer: C

Rationale: Stridor is the sound produced by turbulent airflow through a partially obstructed upper airway. It is a classic sign of upper airway obstruction. While an elongated expiratory phase may indicate lower airway obstruction, stridor specifically points to an upper airway issue. Retractions are also often seen in upper airway obstruction due to the increased effort of breathing. Expiratory wheezing, on the other hand, is more indicative of lower airway conditions such as asthma or chronic obstructive pulmonary disease (COPD).

2. Which of these actions illustrates the correct technique for a nurse when assessing oral temperature with a glass thermometer?

A. Wait 30 minutes if the patient has ingested hot or iced liquids.
B. Leave the thermometer in place for 3 to 4 minutes if the patient is afebrile.
C. Shake the glass thermometer down to 35.5�C before taking the patient's temperature.
D. Place the thermometer at the base of the tongue and ask the patient to close his or her lips.

Correct answer: B

Rationale: The correct technique for assessing oral temperature with a glass thermometer involves leaving the thermometer in place for 3 to 4 minutes if the patient is afebrile and up to 8 minutes if the patient is febrile. Waiting 30 minutes if the patient has ingested hot or iced liquids is incorrect; instead, the nurse should wait 15 minutes in such cases. Shaking the glass thermometer down to 35.5�C, not 37.5�C, is the correct procedure before taking the patient's temperature. Placing the thermometer at the base of the tongue, not the front, and asking the patient to close their lips is the proper way to position the thermometer. Therefore, the correct answer is to leave the thermometer in place for 3 to 4 minutes if the patient is afebrile and up to 8 minutes if the patient is febrile.

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. How many cc are there in 25 ounces?

A. 250
B. 500
C. 750
D. 1000

Correct answer: C

Rationale: To convert ounces to cc, we know that there are 30 cc in 1 ounce. Therefore, to find out how many cc are in 25 ounces, we multiply 30 cc/ounce by 25 ounces which equals 750 cc. This makes choice C, 750, the correct answer. Choices A, B, and D are incorrect as they do not correctly convert ounces to cc.

5. A patient is asked to abduct her arms. Which of the following accurately describes her arm movement?

A. She moves her arms away from her trunk
B. She moves her arms toward her trunk
C. She rotates her arms at the wrists while holding them away from her body
D. She crosses her arms over her abdomen

Correct answer: A

Rationale: Abduction refers to moving a body part away from the midline of the body. In this case, when the patient abducts her arms, she is moving them away from her trunk. Choice A is correct. Choices B, C, and D are incorrect. Choice B describes adduction, which is the movement of a body part toward the midline. Choice C describes wrist rotation, not arm abduction. Choice D describes crossing the arms over the abdomen, which is not the movement associated with abduction.
