1. What is a causative factor of Hirschsprung disease?
- A. Frequent evacuation of solids, liquid, and gases
- B. Excessive peristaltic movement
- C. The absence of parasympathetic ganglion cells in a portion of the colon
- D. One portion of the bowel telescoping into another
Correct answer: C
Rationale: The correct answer is C: The absence of parasympathetic ganglion cells in a portion of the colon is a causative factor of Hirschsprung disease. This absence leads to the inability of the affected segment of the colon to relax, causing a functional obstruction. Choices A, B, and D are incorrect. Frequent evacuation of solids, liquid, and gases, excessive peristaltic movement, and one portion of the bowel telescoping into another are not causative factors of Hirschsprung disease.
2. Postoperative orders for a client undergoing a mitral valve replacement include monitoring pulmonary artery pressure together with pulmonary capillary wedge pressure with a pulmonary artery catheter. This action by the nurse will assess
- A. Right ventricular pressure
- B. Left ventricular end-diastolic pressure
- C. Acid-Base balance
- D. Coronary artery stability
Correct answer: B
Rationale: The correct answer is B: Left ventricular end-diastolic pressure. Pulmonary capillary wedge pressure is used to assess left ventricular end-diastolic pressure. This measurement provides valuable information on the filling pressure of the left ventricle. Choices A, C, and D are incorrect because monitoring pulmonary capillary wedge pressure does not directly assess right ventricular pressure, acid-base balance, or coronary artery stability.
3. If a security officer is reviewing actions to take in the event of a bomb threat by phone to a group of nurses, which statement by a nurse indicates understanding?
- A. “I will get the caller off the phone as soon as possible so I can alert the staff.”
- B. “I will begin evacuating clients using the elevators.”
- C. “I will not ask any questions and just let the caller talk.”
- D. “I will listen for background noises.”
Correct answer: D
Rationale: The correct answer is D: “I will listen for background noises.” Listening for background noises can provide useful information about the bomb’s location, helping security to assess the situation more effectively. Choice A is incorrect because disconnecting the call abruptly may prevent gathering important details. Choice B is incorrect as using elevators during a bomb threat can be dangerous; it is safer to use stairs for evacuation. Choice C is incorrect because actively engaging with the caller to gather information is crucial in bomb threat situations.
4. A client is being taught how to self-administer daily low-dose heparin injections. Which of the following factors is most likely to increase the client’s motivation to learn?
- A. The client’s belief that his needs will be met through education
- B. The nurse’s empathy regarding the client's self-injection
- C. The client seeking family approval by agreeing to a teaching plan
- D. The nurse explaining the need for education to the client
Correct answer: A
Rationale: The client's belief that his needs will be met through education is the most likely factor to increase motivation to learn. When individuals perceive that their educational efforts will directly benefit them, they are more motivated to engage in the learning process. Empathy from the nurse, seeking family approval, or the nurse explaining the need for education may not be as directly tied to the client's personal benefit and may not necessarily increase motivation to learn.
5. When assessing a client with acute asthma, the nurse is most likely to obtain which finding?
- A. Pursed lip breathing and clubbing of fingers
- B. Fever and a high-pitched inspiratory stridor
- C. A short expiratory phase and hemoptysis
- D. Cough and musical breath sounds on expiration
Correct answer: D
Rationale: When assessing a client with acute asthma, a cough and wheezing or musical breath sounds on expiration are typical findings. Pursed lip breathing and clubbing of fingers (choice A) are not common in acute asthma but could be seen in chronic respiratory conditions. Fever and high-pitched inspiratory stridor (choice B) are more indicative of croup or epiglottitis. A short expiratory phase and hemoptysis (choice C) are not typical findings in acute asthma.
