Reye's syndrome, a potentially fatal illness associated with liver failure and encephalopathy is associated with the administration of which over-the-counter (OTC) medication?

Correct Answer: C

Rationale: Reye's syndrome is linked to the use of aspirin in children and adolescents, particularly during viral infections. It causes severe liver and brain damage. Acetaminophen, ibuprofen, and antihistamines are not associated with this condition. Avoiding aspirin in pediatric patients is critical to prevent this rare but life-threatening syndrome.

Correct Answer: A

Rationale: Metformin belongs to the class of medications known as biguanides. Biguanides work primarily by decreasing glucose production in the liver and increasing insulin sensitivity in peripheral tissues, such as muscles. They also help improve glucose uptake and utilization by cells, leading to better control of blood sugar levels. Metformin is commonly used to treat type 2 diabetes mellitus and can also be used in the management of polycystic ovary syndrome (PCOS).

Correct Answer: C

Rationale: In the scenario described, the patient with a history of heart failure (HF) is presenting with symptoms of difficulty breathing, cough, and edema of the lower extremities. These signs and symptoms suggest acute decompensated heart failure (ADHF), which is characterized by a decrease in cardiac output and inadequate tissue perfusion. In this situation, the nurse would anticipate the administration of a positive inotrope medication.

Correct Answer: C

Rationale: The most common side effect that is normal with the initial therapy of Nitroglycerine due to increased vasodilation is a headache. Nitroglycerine causes vasodilation of blood vessels, including the blood vessels in the head and brain. This can lead to headaches as a result of the increased blood flow and changes in blood vessel diameter. Headaches caused by Nitroglycerine are usually mild and transient. It is important to monitor patients for this expected side effect and educate them about it to ensure compliance with the medication regimen.

Correct Answer: A

Rationale: A. Daily weight should be monitored for patients taking diuretics because diuretics can cause fluid loss which may lead to weight changes. Fluctuations in weight can indicate changes in fluid balance and help determine the effectiveness of the diuretic therapy.

Correct Answer: A

Rationale: Fatigue is a common side effect of chemotherapy and can be caused by various factors, including anemia, poor nutrition, sleep disturbances, or psychological stress. The nurse's first step should be to assess for underlying causes of fatigue, such as trouble sleeping, anemia, or depression. Once the cause is identified, appropriate interventions can be implemented, such as dietary changes, sleep hygiene strategies, or treatment for anemia. Encouraging excessive daytime sleep or strenuous exercise without assessment may worsen fatigue or lead to other complications.

Correct Answer: C

Rationale: The appropriate nursing diagnosis for a patient receiving antidysrhythmics would be Deficient fluid volume. Antidysrhythmics can have side effects such as electrolyte imbalances, which can lead to fluid volume deficit. Monitoring the patient's fluid intake and output is crucial to prevent dehydration and maintain proper electrolyte balance. Therefore, identifying Deficient fluid volume as a nursing diagnosis allows for appropriate interventions to be implemented to address and prevent this potential complication.

Correct Answer: D

Rationale: A spirit is an alcoholic or hydroalcoholic solution of volatile substances obtained by distillation. It is commonly used in the production of alcoholic beverages and in the pharmaceutical industry for preparing tinctures and extracts. Spirits are characterized by their high alcohol content and ability to extract and preserve the properties of the substances they are derived from. Decoction is a method of extracting compounds from plants using boiling water, fluid extract is a concentrated liquid extract of a substance, solution refers to a homogeneous mixture of substances, and syrup is a thick, sweet liquid usually made by dissolving sugar in water.

Correct Answer: D

Rationale: The correct statement is that the heparin provides anticoagulation until therapeutic levels of warfarin are reached. Heparin and warfarin are both anticoagulants but work in different ways. Heparin acts quickly to prevent blood clot formation while warfarin takes several days to reach its full effect. Therefore, heparin is often used initially to provide immediate anticoagulation while waiting for the warfarin to reach therapeutic levels. This dual therapy is common in clinical practice to ensure continuous anticoagulation.
