A nurse in a provider's clinic is assessing a client who takes sublingual nitroglycerin for stable angina. The client reports getting a headache each time he takes the medication. Which of the following statements should the nurse make?
"Take only one dose of nitroglycerin to reduce the risk of getting a headache."
"We will ask the provider to prescribe a different medication for you."
"There's nothing that can be done to relieve the headaches that nitroglycerin causes."
"Try taking a mild analgesic to relieve the headache."
The Correct Answer is D
Choice A reason: Taking only one dose of nitroglycerin is not a good advice, as it may not be enough to relieve the angina pain and prevent a myocardial infarction. Nitroglycerin is a vasodilator that relaxes the blood vessels and improves the blood flow to the heart. The recommended dose is one tablet or spray under the tongue every 5 minutes for up to three doses, or until the pain is relieved. Taking only one dose may compromise the effectiveness of the medication and the safety of the client.
Choice B reason: Asking the provider to prescribe a different medication is not a necessary action, as nitroglycerin is a first-line treatment for stable angina and has proven benefits for reducing mortality and morbidity. Changing the medication may not be appropriate or feasible, as there may not be a suitable alternative that has the same efficacy and safety profile. The client should continue taking nitroglycerin as prescribed, unless the provider decides otherwise.
Choice C reason: Saying that there's nothing that can be done to relieve the headaches is not a true or helpful statement, as there are some measures that can help reduce or prevent the headaches. Headaches are a common and expected side effect of nitroglycerin, as it dilates the blood vessels in the brain and causes increased intracranial pressure. However, the headaches usually subside over time as the body adapts to the medication. The client can also take a mild analgesic, such as acetaminophen or ibuprofen, to relieve the headache, as long as it does not interact with the nitroglycerin or other medications.
Choice D reason: Trying to take a mild analgesic to relieve the headache is a reasonable and appropriate suggestion, as it can help alleviate the discomfort and improve the quality of life of the client. The client should choose an analgesic that is safe and effective, such as acetaminophen or ibuprofen, and follow the directions on the label. The client should also consult the provider or the pharmacist before taking any over-the-counter medications, as some of them may interact with nitroglycerin or other medications. The client should also avoid aspirin, as it may increase the risk of bleeding.

Correct Answer is B
Explanation
Choice A reason: Taking the medication in the morning is not the correct instruction. Simvastatin is a statin drug that lowers cholesterol levels by inhibiting the enzyme that produces cholesterol in the liver. The liver produces more cholesterol at night, so simvastatin is more effective when taken in the evening or at bedtime.
Choice B reason: Avoiding grapefruit juice is the correct instruction. Grapefruit juice can increase the blood levels of simvastatin and cause serious side effects such as muscle damage, liver damage, and kidney failure. Grapefruit juice inhibits the enzyme that metabolizes simvastatin in the intestine, leading to higher concentrations of the drug in the bloodstream.
Choice C reason: Monitoring for ringing in the ears is not the correct instruction. Ringing in the ears, or tinnitus, is not a common or serious side effect of simvastatin. However, some other medications that lower cholesterol, such as niacin and gemfibrozil, can cause tinnitus. The client should report any unusual or persistent symptoms to the prescriber.
Choice D reason: Expecting brown-colored urine is not the correct instruction. Brown-colored urine, or hematuria, is not a normal or expected side effect of simvastatin. However, it may indicate a serious condition such as rhabdomyolysis, which is a rare but life-threatening complication of statin therapy. Rhabdomyolysis is the breakdown of muscle tissue that releases a protein called myoglobin into the bloodstream. Myoglobin can damage the kidneys and cause brown-colored urine. The client should seek immediate medical attention if they notice any signs of rhabdomyolysis, such as muscle pain, weakness, fever, or dark urine.
Correct Answer is B
Explanation
Choice A - Catheter Occlusion: This occurs when the catheter is blocked, preventing the flow of fluids or medication. It is usually indicated by difficulty in flushing the catheter or a slow drip rate¹. However, it does not typically cause a gurgling sound.
Choice B - (Catheter migration) is correct because when a central venous catheter (CVC) migrates from its original position, the tip can enter a smaller vein or a different location where turbulence occurs. This may cause the client to hear a gurgling or bubbling sound, especially during infusion or with position changes. Migration can happen due to coughing, movement, or changes in pressure, and it doesn’t necessarily involve the catheter being visibly out of place
Choice C - (Catheter dislodgment) is incorrect because dislodgment typically refers to the catheter being partially pulled out of the insertion site. This would be more likely to cause external signs like visible catheter movement or fluid leakage at the insertion site, rather than internal gurgling sounds. Gurgling is more associated with internal changes in catheter position, as seen with migration.
Choice D - Catheter Rupture: This is a break or tear in the catheter. It can cause serious complications, including infection and embolism. However, a gurgling sound is not a typical symptom of a catheter rupture¹.
