Question 1 of 5
A nurse is preparing to administer enoxaparin subcutaneously to a client using a prefilled syringe. The nurse should plan to use which of the following techniques when administering this medication?
Correct Answer: D
Rationale:
Correct
Answer: D. Inject the medication into abdominal tissue.
Rationale: Enoxaparin is a low molecular weight heparin that is typically administered subcutaneously. The abdomen is a common and recommended injection site for subcutaneous injections due to the abundant subcutaneous tissue, allowing for proper absorption and minimizing the risk of tissue damage or nerve injury. Additionally, rotating injection sites helps prevent tissue irritation.
Incorrect
Choices:
A: Aspirating prior to injecting the medication is not necessary for subcutaneous injections as it is for intramuscular injections.
B: Gently massaging the site following the injection is not recommended as it may lead to bruising or discomfort.
C: Expelling air bubbles is more relevant for intravenous injections and not typically necessary for subcutaneous injections.
Question 2 of 5
A nurse who is preparing to administer medications to a client is unfamiliar with a medication that the client takes at home. Which of the following resources should the nurse consult?
Correct Answer: D
Rationale: The correct answer is D: Nursing drug guide. Consulting a nursing drug guide is essential for verifying medication information, such as indications, dosage, side effects, and contraindications. It provides comprehensive and accurate information to ensure safe medication administration. Pharmaceutical sales representatives may have biased information and are not healthcare professionals. Nursing team members may not have the specific knowledge required. The client's family may not have accurate information and may not be reliable sources for medication details. Consulting a nursing drug guide is the most reliable and evidence-based resource for medication information.
Question 3 of 5
A nurse is preparing to administer a levothyroxine 50 mcg tablet PO to a client who is receiving an enteral feeding through an NG tube. Which of the following actions should the nurse take?
Correct Answer: A
Rationale: The correct answer is A: Dissolve the medication in 30 mL of water. Levothyroxine should be dissolved in water before administering through an NG tube to prevent tube blockage and ensure proper absorption. Dissolving the medication in water helps to prevent clogging of the tube and ensures accurate dosing. It is crucial to follow medication guidelines to prevent complications. Maintaining the client in the supine position (
B) is not necessary for this medication administration. Adding the medication to the enteral feeding formula (
C) may alter the medication's absorption and effectiveness. Flushing the tube with water after administering the medication (
D) is a good practice but is not the primary action needed in this situation.
Question 4 of 5
A nurse is collecting data from a client who has been taking diazepam several times per day but recently ran out of the medication. Which of the following findings should the nurse recognize as a manifestation of withdrawal from diazepam?
Correct Answer: D
Rationale: The correct answer is D: Tremors. Withdrawal from diazepam, a benzodiazepine, can lead to physical symptoms such as tremors due to the sudden absence of the drug in the body. This occurs because diazepam suppresses the central nervous system, and abrupt discontinuation can result in rebound hyperactivity of the nervous system, leading to tremors. Hypotension (
A) is not a typical withdrawal symptom of diazepam, as it is more commonly associated with opioid withdrawal. Drowsiness (
B) is actually a side effect of diazepam, so experiencing drowsiness would be more likely when the client is taking the medication rather than during withdrawal. Anorexia (
C) is not a common withdrawal symptom of diazepam; instead, it may cause increased appetite.
Therefore, the presence of tremors is the most indicative of withdrawal from diazepam in this scenario.
Question 5 of 5
A nurse is preparing to administer digoxin to a client. For which of the following findings should the nurse withhold the medication?
Correct Answer: A
Rationale: The correct answer is A. The nurse should withhold digoxin if the apical pulse is below 60 beats/min in adults. This is because digoxin can cause bradycardia, so administering it when the pulse is already low can lead to further slowing of the heart rate and potential adverse effects like arrhythmias.
Choices B, C, and D are not reasons to withhold digoxin as they are within normal ranges for respiratory rate, blood pressure, and temperature. It's important to monitor these parameters but they do not indicate a need to withhold the medication.
