When teaching a patient about self-administration of insulin, what is the most important instruction to provide?

Correct Answer: A

Rationale: The most important instruction to provide when teaching a patient about self-administration of insulin is to rotate injection sites to prevent tissue damage. Rotating injection sites helps prevent lipodystrophy (tissue damage) and ensures proper insulin absorption. Option B is incorrect because the angle of insulin injection varies depending on the patient's body composition. Injecting at a 90-degree angle is not always necessary. Option C is not the most crucial instruction; while storing insulin in the refrigerator is important, it is not the priority when teaching self-administration. Option D is also important for maintaining consistency but is not as critical as rotating injection sites to prevent tissue damage.

Correct Answer: C

Rationale: The correct answer is C. Using a clean technique for inserting a urinary catheter increases the risk for healthcare-associated infections. Invasive procedures like catheter insertion require a sterile technique to prevent introducing pathogens into the urinary tract. Choices A and B demonstrate appropriate infection control measures by emphasizing the use of sterile or aseptic techniques. Choice D represents an incorrect technique that can lead to the introduction of bacteria from the rectum into the urinary tract, potentially causing infections.

Correct Answer: B

Rationale: Administering oxygen at 2 liters per minute via nasal cannula is the immediate action for a patient experiencing shortness of breath. This intervention helps to improve oxygenation and relieve respiratory distress promptly. Placing the patient in a high Fowler's position (choice A) may also be beneficial but providing oxygen takes precedence in this scenario to address the underlying hypoxemia. Encouraging deep breaths and coughing (choice C) may not be appropriate as the first action, especially without assessing the patient first. Assessing lung sounds (choice D) is essential but should follow the initial intervention of administering oxygen.

Correct Answer: B

Rationale: If a nurse manager assigns a nursing assistant a task that is outside of their role, the nursing assistant should report the task to the charge nurse. This is important because the charge nurse can provide guidance on whether the task is appropriate for the nursing assistant to perform. Choice A is incorrect because blindly following a directive that is outside of the nursing assistant's scope could lead to negative consequences. Choice C might not be the best course of action initially, as it's important to seek clarification first. Choice D is also not the best option because performing a task outside of one's role without proper authorization can pose risks to both the patient and the nursing assistant.

Correct Answer: A

Rationale: The correct answer is A. A reduction in the need for analgesic medication indicates that guided imagery is effective in managing the patient's pain. Choices B, C, and D do not directly measure the effectiveness of guided imagery. A patient rating pain as 6 on a scale of 0 to 10, asking for pain medication once, or having stoic facial expressions may not necessarily reflect the impact of guided imagery on pain management.

Correct Answer: B

Rationale: The correct answer is B: 'Flush the NG tube before and after each medication.' Flushing the NG tube is essential to ensure that the medication passes through smoothly without any obstruction. It helps prevent clogging of the tube and ensures that the full dose of the medication reaches the patient. Options A, C, and D are incorrect because crushing all medications at once, administering only liquid forms of medications, and skipping tube flushing entirely can lead to complications such as tube blockages, incomplete medication administration, and potential harm to the client.

Correct Answer: D

Rationale: Corrected Rationale: When a patient is prescribed a diuretic for hypertension, monitoring the patient's sodium levels is crucial. Diuretics can lead to alterations in sodium levels, potentially causing complications like hyponatremia. While monitoring other parameters like respiratory rate, blood pressure, and potassium levels may also be important, the primary concern with diuretic therapy is the risk of sodium imbalance, making the monitoring of sodium levels the most critical assessment.

Correct Answer: B

Rationale: The nurse's priority action should be to withhold the medication until the trough level is obtained. This is crucial to ensure accurate dosing based on the patient's levels. Administering the medication before the peak level is obtained (choice A) can lead to incorrect dosing. Administering the medication based on the previous trough level (choice C) may not reflect the current levels accurately. Ensuring that the medication is administered within 2 hours of the peak level (choice D) is not necessary for obtaining accurate peak and trough levels.

Correct Answer: D

Rationale: The correct answer is to call the provider for clarification. When faced with a higher-than-usual dose of medication, the nurse's first action should be to contact the prescribing healthcare provider to confirm the dosage. Administering the medication without clarifying the dose with the provider can pose serious risks to the patient's safety. Holding the medication and consulting the pharmacist may be appropriate after contacting the provider for clarification. Asking another nurse to verify the dose is not the most appropriate action when dealing with an unusual prescription; direct communication with the provider is essential in such situations.
