1. A client with a new prescription for simvastatin is receiving teaching from a healthcare provider. Which of the following statements by the client indicates an understanding of the teaching?
- A. 'I should take this medication in the evening.'
- B. 'I should avoid drinking grapefruit juice.'
- C. 'I should expect my urine to be red-orange while taking this medication.'
- D. 'I will need to take this medication for the rest of my life.'
Correct answer: A
Rationale: The correct answer is A. Taking simvastatin in the evening is recommended because cholesterol synthesis increases at night. This timing maximizes the effectiveness of the medication in lowering cholesterol levels. Choice B is incorrect because grapefruit juice should be avoided with certain statins, but simvastatin is not significantly affected by grapefruit juice. Choice C is incorrect as red-orange urine is not an expected side effect of simvastatin. Choice D is incorrect because simvastatin is typically prescribed for managing cholesterol levels and may not need to be taken for the rest of the client's life.
2. A healthcare professional is providing discharge teaching to a client who has a new prescription for enoxaparin. Which of the following instructions should the healthcare professional include?
- A. Administer the injection into the abdomen.
- B. Avoid massaging the injection site after administration.
- C. Expect mild bruising at the injection site.
- D. Avoid alternating injection sites between the arms.
Correct answer: A
Rationale: Administering enoxaparin into the abdomen is recommended to ensure proper absorption and effectiveness. Massaging the injection site after administration should be avoided as it can increase the risk of bleeding or bruising. Mild bruising at the injection site is common with enoxaparin and should be expected. Alternating injection sites, especially between arms, is not suitable for enoxaparin administration. Consistent administration into the abdomen is preferred for consistent absorption of the medication.
3. The client is being taught about the use of sublingual nitroglycerin for chest pain. Which instruction should be provided?
- A. Swallow the tablet whole with water.
- B. Place the tablet under the tongue and let it dissolve.
- C. Chew the tablet and then swallow.
- D. Place the tablet between the cheek and gum.
Correct answer: B
Rationale: The correct method for administering sublingual nitroglycerin is to place the tablet under the tongue and allow it to dissolve. This route of administration facilitates rapid absorption of the medication into the bloodstream, enabling quick relief of chest pain associated with angina or heart conditions. Choice A is incorrect because sublingual nitroglycerin should not be swallowed whole. Choice C is wrong as chewing the tablet can lead to the rapid release of the drug, causing adverse effects like headaches or dizziness. Choice D is also incorrect as the tablet should not be placed between the cheek and gum, but under the tongue for proper absorption.
4. A client has a new prescription for sertraline. Which of the following instructions should the nurse include?
- A. Take the medication in the morning.
- B. Avoid consuming grapefruit juice.
- C. Take the medication with a full glass of water.
- D. Monitor for signs of weight gain.
Correct answer: B
Rationale: The correct instruction for the nurse to include is to 'Avoid consuming grapefruit juice.' Grapefruit juice can increase sertraline levels, leading to an elevated risk of side effects. Instructing the client to avoid grapefruit juice is crucial to prevent potential interactions that could impact the effectiveness and safety of the medication. The other options are not directly related to sertraline administration. Taking the medication in the morning may vary depending on individual preferences or the prescriber's directions. Taking the medication with a full glass of water is a general instruction for many medications and not specific to sertraline. Monitoring for signs of weight gain is important but not a direct instruction related to taking sertraline.
5. The nurse is assisting with the care of a client who is on a continuous heparin infusion for deep vein thrombosis (DVT). Which laboratory test should the nurse monitor to evaluate the effectiveness of the therapy?
- A. Prothrombin time (PT)
- B. Activated partial thromboplastin time (aPTT)
- C. International normalized ratio (INR)
- D. Platelet count
Correct answer: B
Rationale: To evaluate the effectiveness of heparin therapy in a client with DVT, the nurse should monitor the activated partial thromboplastin time (aPTT). The aPTT test helps ensure that the dose of heparin is within the therapeutic range, which is essential for preventing clot formation or excessive bleeding. Monitoring aPTT is crucial in managing patients on heparin therapy to maintain the delicate balance between preventing thrombosis and avoiding hemorrhage. Prothrombin time (PT) and International normalized ratio (INR) are more indicative of warfarin therapy effectiveness, not heparin. Platelet count assesses platelet levels and function, not the effectiveness of heparin therapy for DVT.
