The nurse is assessing a client who has a prescription for digoxin (Lanoxin). Which finding indicates that the client is at risk for digoxin toxicity?
- A. Heart rate of 60 beats per minute
- B. Blood pressure of 120/80 mm Hg
- C. Respiratory rate of 18 breaths per minute
- D. Serum potassium level of 3.0 mEq/L
Correct Answer: D
Rationale: A low serum potassium level increases the risk of digoxin toxicity. Digoxin toxicity is more likely to occur in individuals with low potassium levels because potassium is crucial for proper heart function. A heart rate of 60 beats per minute, blood pressure of 120/80 mm Hg, and respiratory rate of 18 breaths per minute are within normal ranges and do not directly indicate an increased risk of digoxin toxicity.

A nurse is preparing to administer an intramuscular injection to a client. Which action should the nurse take to reduce the client's risk of injury?
- A. Use a 1-inch needle
- B. Select a large muscle for the injection
- C. Aspirate for blood return before injecting
- D. Massage the injection site
Correct Answer: C
Rationale: The correct answer is to aspirate for blood return before injecting. This action helps ensure that the needle is not in a blood vessel, reducing the risk of injury. Using a 1-inch needle (Choice A) is a standard length for intramuscular injections but does not directly reduce the risk of injury. Selecting a large muscle for the injection (Choice B) is important for proper medication absorption but does not directly reduce the risk of injury. Massaging the injection site (Choice D) can help with medication absorption but does not reduce the risk of injury.
The nurse in a community health clinic is interviewing a female client who has three children. The client tells the nurse that she has a new man in her life, with whom she is having a sexual relationship, and that they both smoke cigarettes. Which information is most important for the nurse to provide this client?
- A. Oral contraceptives should be started to prevent an unwanted pregnancy
- B. Children are more prone to upper respiratory infections if exposed to smoke at home
- C. Cigarette smoking increases the risk for peptic ulcers and emphysema
- D. A diaphragm and condom provide effective contraception when used together
Correct Answer: D
Rationale: The most important information for the nurse to provide the client in this situation is that using both a diaphragm and a condom together provides effective contraception and also protects against sexually transmitted diseases (STDs). While oral contraceptives can help prevent unwanted pregnancies, using a barrier method like a diaphragm and a condom is crucial in this scenario where the client is engaging in a new sexual relationship. Choice B is important information but is not the top priority in this context. Choice C, although relevant, does not address the immediate concern of contraception and STD prevention. Therefore, the correct answer is D.
The nurse is preparing to administer medications to a client with a nasogastric tube. Which action should the nurse take first?
- A. Check for tube placement
- B. Crush the medications
- C. Flush the tube with water
- D. Administer the medications
Correct Answer: A
Rationale: The correct first action when administering medications to a client with a nasogastric tube is to check for tube placement. This is crucial to ensure that the medications are delivered to the correct location within the gastrointestinal tract. Checking the tube placement helps prevent complications such as medication entering the lungs if the tube is misplaced. Crushing the medications (choice B) or flushing the tube with water (choice C) should only be done after confirming the correct tube placement. Administering the medications (choice D) without verifying the tube placement can lead to serious consequences.
The client is being taught how to take alendronate (Fosamax) for osteoporosis treatment. Which statement indicates that the client needs further teaching?
- A. I should take this medication at bedtime
- B. I will need to take this medication for at least 3 years
- C. I should sit up for 30 minutes after taking the medication
- D. I should take this medication with a full glass of water
Correct Answer: A
Rationale: The correct answer is A because taking Fosamax at bedtime is incorrect. It should be taken in the morning with a full glass of water to prevent esophageal irritation. Choice B is correct; alendronate is typically taken for several years to treat osteoporosis. Choice C is correct as remaining upright for 30 minutes after taking Fosamax helps prevent esophageal irritation. Choice D is also correct as taking alendronate with a full glass of water is necessary to ensure proper absorption.
Several clients on a telemetry unit are scheduled for discharge in the morning, but a telemetry-monitored bed is needed immediately. The charge nurse should make arrangements to transfer which client to another medical unit?
- A. Learning to self-administer insulin injections after being diagnosed with diabetes mellitus
- B. Ambulatory following coronary artery bypass graft surgery performed six days ago
- C. Wearing a sling immobilizer following permanent pacemaker insertion earlier that day
- D. Experiencing syncopal episodes resulting from the dehydration caused by severe diarrhea
Correct Answer: A
Rationale: The correct answer is A because transferring a stable client who is learning self-care, such as self-administering insulin injections after being diagnosed with diabetes mellitus, provides the needed telemetry-monitored bed without compromising the client's care. Choice B should not be transferred as the client is ambulatory following surgery and does not require telemetry monitoring. Choice C should not be transferred as the client is wearing a sling immobilizer following pacemaker insertion, which requires close monitoring. Choice D should not be transferred as the client is experiencing syncopal episodes due to severe dehydration, necessitating telemetry monitoring for immediate intervention.
