A client with a diagnosis of myocardial infarction (MI) is prescribed nitroglycerin. What is the primary action of this medication?
- A. Increases heart rate
- B. Lowers blood pressure
- C. Dilates coronary arteries
- D. Reduces myocardial oxygen demand
Correct Answer: C
Rationale: The correct answer is C: Nitroglycerin dilates coronary arteries, improving blood flow to the heart muscle. This helps increase oxygen supply to the heart tissue. Option A, 'Increases heart rate,' is incorrect because nitroglycerin does not directly affect heart rate. Option B, 'Lowers blood pressure,' is also incorrect as while nitroglycerin can lower blood pressure, its primary action in the context of MI is related to coronary artery dilation. Option D, 'Reduces myocardial oxygen demand,' is not the primary action of nitroglycerin in the treatment of myocardial infarction; its main action is to increase oxygen supply by dilating coronary arteries.

A client with a history of asthma is experiencing wheezing and shortness of breath. What is the priority nursing intervention?
- A. Administer a bronchodilator as prescribed
- B. Encourage the client to drink fluids
- C. Place the client in an upright position
- D. Assess the client's peak flow rate
Correct Answer: A
Rationale: Administering a bronchodilator as prescribed is the priority nursing intervention for a client experiencing wheezing and shortness of breath due to asthma. Bronchodilators help relieve bronchoconstriction, allowing better airflow and improving breathing. Encouraging the client to drink fluids may be beneficial in certain situations, but it is not the priority when the client is in respiratory distress. Placing the client in an upright position, not supine, can facilitate easier breathing by allowing the chest to expand fully. While assessing the client's peak flow rate is important in asthma management, in this acute situation, the priority is to provide immediate relief by administering the bronchodilator.
The nurse observes that a male client's urinary catheter (Foley) drainage tubing is secured with tape to his abdomen and then attached to the bed frame. What action should the nurse implement?
- A. Raise the bed to ensure the drainage bag remains off the floor
- B. Attach the drainage bag to the side rail instead of the bed frame
- C. Observe the appearance of the urine in the drainage tubing
- D. Secure the tubing to the client's gown instead of his abdomen
Correct Answer: D
Rationale: The correct action for the nurse to implement is to secure the tubing to the client's gown instead of his abdomen. Securing the tubing to the client's abdomen can cause discomfort, trauma to the urethra, and increase the risk of infection. Attaching the drainage bag to the bed frame can lead to tension on the catheter, increasing the risk of dislodgement or trauma. Raising the bed does not address the issue of incorrect tubing securing. Observing the appearance of urine is important but secondary to ensuring proper tubing attachment.
After a 26-year-old gravida 4, para 0 experienced a spontaneous abortion at 9 weeks gestation, how should the nurse intervene after observing the client crying softly one hour post dilation and curettage (D&C)?
- A. Offer to call the social worker to discuss the possibility of adoption
- B. Reassure the client that the infertility specialist can help
- C. Express sorrow for the client's grief and offer to sit with her
- D. Chart the vital signs and amount of vaginal bleeding
Correct Answer: C
Rationale: After a traumatic experience like a spontaneous abortion, it is crucial for the nurse to provide emotional support. Expressing sorrow for the client's grief and offering to sit with her demonstrates empathy and allows the client to process her emotions. Options A and B focus on future possibilities and medical interventions, which may not be immediately appropriate. Option D, while important for monitoring the client's physical status, does not address the client's emotional needs at that moment.
What is the most important action to prevent complications while caring for a client receiving enteral nutrition via a nasogastric tube?
- A. Check tube placement before each feeding
- B. Flush the tube with water before and after each feeding
- C. Elevate the head of the bed to 30 degrees
- D. Administer the feeding at room temperature
Correct Answer: A
Rationale: Checking tube placement before each feeding is crucial to prevent aspiration, a serious complication of enteral nutrition. Ensuring the tube is correctly positioned in the stomach helps avoid the risk of the feeding going into the lungs, which can lead to aspiration pneumonia. Flushing the tube with water (Choice B) is important for maintaining tube patency but is not the most critical action to prevent complications. Elevating the head of the bed (Choice C) helps reduce the risk of aspiration but is not as crucial as verifying tube placement. Administering the feeding at room temperature (Choice D) is more related to patient comfort and does not directly address the prevention of complications associated with enteral nutrition via a nasogastric tube.
The nurse is caring for a client with a tracheostomy who is on mechanical ventilation. What is the priority nursing intervention?
- A. Suction the tracheostomy as needed
- B. Ensure the tracheostomy ties are secure
- C. Provide humidified oxygen
- D. Clean any exudate around the tracheostomy site
Correct Answer: A
Rationale: The priority nursing intervention for a client with a tracheostomy on mechanical ventilation is to suction the tracheostomy as needed. Suctioning is essential to maintain a clear airway and prevent respiratory distress. While ensuring tracheostomy ties are secure (choice B) is important, it is not as urgent as airway maintenance. Providing humidified oxygen (choice C) is beneficial but does not address the immediate need for airway clearance. Cleaning exudate around the tracheostomy site (choice D) is important for hygiene but takes precedence over ensuring airway patency through suctioning.
