NurseDive Free Nursing Practice Question
A nurse on a telemetry unit is assessing a client who is receiving continuous cardiac monitoring. The client's heart rate is 69/min and the PR interval is 0.24 seconds. The nurse should interpret this finding as which of the following cardiac rhythms?
A. Atrial fibrillation
Atrial fibrillation is characterized by a rapid, irregular heartbeat and an absence of distinct P waves on the ECG, which is not indicated by the information provided.
B. First-degree AV block
First-degree AV block is indicated by a prolonged PR interval without affecting the overall heart rate, aligning with the client’s PR interval of 0.24 seconds.
C. Premature ventricular contraction
Premature ventricular contraction would show an abnormal QRS complex on the ECG, which is not mentioned in the scenario.
D. Sinus bradycardia
Sinus bradycardia is defined by a heart rate less than 60 bpm, which does not apply here as the client’s heart rate is 69/min, within the normal range of 60-100 bpm.

A nurse is caring for an adolescent client who has cystic fibrosis. Which of the following actions should the nurse instruct the client to take prior to initiating postural drainage?
A. Complete oral hygiene.
Completing oral hygiene is important for overall health, especially for individuals with cystic fibrosis, as they are at a higher risk for dental problems due to thick mucus that can harbor bacteria. However, oral hygiene does not have a direct impact on the effectiveness of postural drainage. Postural drainage is a technique used to clear mucus from the lungs, and while maintaining oral hygiene is beneficial, it is not a prerequisite for this procedure.
B. Use an ibuterol inhaler.
Using a bronchodilator, such as an ibuterol inhaler, is recommended before postural drainage because it helps to open the airways, making the procedure more effective. Bronchodilators work by relaxing the muscles around the airways, which can become constricted in conditions like cystic fibrosis. This relaxation allows for easier clearance of mucus during postural drainage.
C. Take pancrelipase.
Pancrelipase is an enzyme supplement used to aid digestion in patients with cystic fibrosis, who often have pancreatic insufficiency. While taking pancrelipase is crucial for nutrient absorption, it is not specifically related to the respiratory treatment of postural drainage. Therefore, it is not necessary to take pancrelipase immediately before this procedure.
D. Eat a meal.
Eating a meal before postural drainage is not recommended. The procedure involves placing the body in positions that facilitate the drainage of mucus from the lungs due to gravity. Having a full stomach can cause discomfort, increase the risk of vomiting, and may hinder the effectiveness of the drainage. It is best to perform postural drainage when the stomach is empty, either before meals or at least 1.5 hours after eating.

A nurse is providing teaching to a client who is to begin external radiation therapy for cancer. Which of the following information should the nurse include?
A. "You might experience altered taste sensations."
"You might experience altered taste sensations" is the correct statement. When providing teaching to a client about to undergo external radiation therapy for cancer, the nurse should include information about potential side effects and what to expect during the treatment. One common side effect of radiation therapy, especially when the treatment is focused on or near the head and neck region, is altered taste sensations. Radiation can affect the taste buds and lead to changes in how foods taste.
B. "Use rubbing alcohol to remove the ink markings."
"Use rubbing alcohol to remove the ink markings. “The statement is incorrect. The ink markings made on the client's skin are used as reference points for the radiation therapy treatment. It is essential not to remove these markings, as they are crucial for accurate positioning during each treatment session. The nurse should instruct the client not to tamper with the markings, and the radiation therapy team will remove them when they are no longer needed.
C. "Wear a binder over the radiation site."
"Wear a binder over the radiation site." The statement is incorrect. Wearing a binder over the radiation site is not a standard practice during external radiation therapy. The client should be instructed to follow the specific guidelines provided by the radiation therapy team regarding clothing and positioning during treatments. The use of binders or other tight clothing over the treatment area may not be recommended, as it can cause discomfort or interfere with the delivery of radiation.
D. "Wash your skin thoroughly with a washcloth after each treatment."
"Wash your skin thoroughly with a washcloth after each treatment." Is incorrect statement. During radiation therapy, the skin in the treatment area can become sensitive. It is essential for the client to follow the specific instructions provided by the radiation therapy team regarding skin care. Generally, the client should avoid using harsh soaps or scrubbing the skin vigorously. Instead, they should gently cleanse the area with a mild soap or as directed by their healthcare providers.

A nurse is providing teaching to an older adult client who has a seizure disorder and a new prescription for phenytoin. Which of the following instructions should the nurse include?
A. "Plan to take this medication with food."
"Plan to take this medication with food." Is the correct statement. When providing instructions to an older adult client who has a seizure disorder and is prescribed phenytoin (an antiepileptic or anticonvulsant medication), the nurse should advise the client to take the medication with food. Phenytoin can cause gastrointestinal irritation, and taking it with food can help minimize this side effect.
B. "Plan to take this medication with antacids."
"Plan to take this medication with antacids. “is not the appropriate instruction. Phenytoin should not be taken with antacids. Antacids can reduce the absorption of phenytoin, leading to decreased effectiveness of the medication. If antacids are needed for other reasons, they should be taken at least 2 hours before or after taking phenytoin.
C. "Limit foods that contain vitamin D while taking this medication."
"Limit foods that contain vitamin D while taking this medication. “This is not inappropriate instruction. There is no specific requirement to limit foods containing vitamin D while taking phenytoin. However, phenytoin may decrease the absorption of vitamin D, which could potentially affect the client's vitamin D levels. Therefore, it is essential for the client to have regular check-ups and possibly discuss the need for vitamin D supplementation with their healthcare provider.
D. "Limit foods that contain folic acid while taking this medication."
"Limit foods that contain folic acid while taking this medication. “This is not the correct statement. Phenytoin can interfere with the absorption of folic acid (a B-vitamin). Long-term use of phenytoin may lead to folic acid deficiency. Therefore, the nurse should instruct the client to consume foods rich in folic acid and discuss the potential need for folic acid supplementation with their healthcare provider.
