A nurse is assessing a client who has hypercholesterolemia and is receiving simvastatin. Which of the following findings should the nurse recognize as a potential adverse effect?
Blurred vision
Orthostatic hypotension
Urinary retention
Muscle weakness
The Correct Answer is D
Choice A reason: Blurred vision is not a common or serious side effect of simvastatin, as it does not affect the eyes or the vision. Blurred vision may be caused by other factors, such as diabetes, hypertension, or eye disorders.
Choice B reason: Orthostatic hypotension is not a common or serious side effect of simvastatin, as it does not affect the blood pressure or the vascular tone. Orthostatic hypotension may be caused by other factors, such as dehydration, anemia, or medication interactions.
Choice C reason: Urinary retention is not a common or serious side effect of simvastatin, as it does not affect the urinary tract or the bladder function. Urinary retention may be caused by other factors, such as prostate enlargement, infection, or nerve damage.
Choice D reason: Muscle weakness is a common and serious side effect of simvastatin, as it can indicate muscle damage or rhabdomyolysis. Rhabdomyolysis is a life-threatening condition that causes the breakdown of muscle tissue and the release of myoglobin into the bloodstream, which can lead to kidney failure. Muscle weakness may be accompanied by muscle pain, tenderness, or dark urine. The nurse should monitor the client's creatine kinase (CK) levels and report any signs of muscle damage to the provider.

Correct Answer is C
Explanation
Choice A reason: Naloxone is not the correct medication. Naloxone is an opioid antagonist that reverses the effects of opioid overdose, such as respiratory depression, sedation, and hypotension. Naloxone has no effect on magnesium sulfate, which is a mineral and electrolyte that is used to prevent seizures in clients with preeclampsia or eclampsia.
Choice B reason: Protamine is not the correct medication. Protamine is a heparin antagonist that reverses the effects of heparin overdose, such as bleeding, bruising, and thrombocytopenia. Protamine has no effect on magnesium sulfate, which is not an anticoagulant.
Choice C reason: Calcium gluconate is the correct medication. Calcium gluconate is a calcium salt that antagonizes the effects of magnesium sulfate overdose, such as hypotension, bradycardia, respiratory depression, and muscle weakness. Calcium gluconate is the antidote for magnesium sulfate toxicity, which can occur when the serum magnesium level is above 7.5 mEq/L. The nurse should monitor the client's vital signs, deep tendon reflexes, and urine output, and report any signs of toxicity to the provider.
Choice D reason: Flumazenil is not the correct medication. Flumazenil is a benzodiazepine antagonist that reverses the effects of benzodiazepine overdose, such as drowsiness, confusion, and coma. Flumazenil has no effect on magnesium sulfate, which is not a sedative.
Correct Answer is A
Explanation
Choice A reason: Using an electric razor while on warfarin is the correct instruction. Warfarin is an anticoagulant that inhibits the formation of blood clots and prolongs the bleeding time. Using an electric razor can reduce the risk of cuts and bleeding while shaving. The client should avoid using sharp objects or instruments that can cause injury or trauma.
Choice B reason: Doubling the dose of warfarin if a dose is missed is not the correct instruction. This is a dangerous and potentially fatal advice, as it can cause overdose and severe bleeding. The client should take the missed dose as soon as possible, unless it is close to the next scheduled dose, in which case the client should skip the missed dose and resume the regular dosing schedule. The client should never take extra doses or change the dose without consulting the provider.
Choice C reason: Mild nosebleeds being common during initial treatment is not the correct instruction. This is a false and misleading statement, as nosebleeds are not a normal or expected side effect of warfarin therapy. Nosebleeds can indicate bleeding problems or complications, such as thrombocytopenia, which is a low platelet count. The client should report any nosebleeds or other signs of bleeding, such as bruising, petechiae, hematuria, or melena, to the provider immediately.
Choice D reason: Increasing fiber intake to reduce the adverse effect of constipation is not the correct instruction. This is an irrelevant and unnecessary recommendation, as constipation is not a common or serious adverse effect of warfarin therapy. Constipation can be caused by many factors, such as diet, hydration, activity, or medication. The client should maintain a balanced and consistent diet, drink plenty of fluids, and exercise regularly to prevent constipation. The client should also avoid foods that are high in vitamin K, such as green leafy vegetables, as they can interfere with the effect of warfarin.
