Question 1 of 5
The nursing instructor teaches the student nurses about the pharmacological classification of drugs. The instructor evaluates that learning has occurred when the students make which response?
Correct Answer: D
Rationale: Pharmacological classification groups drugs by mechanism-anticoagulants influence clotting by inhibiting factors like thrombin, a precise definition. Anti-anginal and antihypertensive describe therapeutic effects, not mechanisms. Calcium channel blockers' action is mechanistic but less broad than clotting's systemic impact. Anticoagulants' specific role in coagulation reflects accurate classification understanding, key for pharmacology learning.
Question 2 of 5
A client with juvenile pilocytic astrocytoma who is receiving dexamethasone (Decadron) 4mg/IV every 6 hours to relieve symptoms of right arm weakness and headache. Which of the following assessments will concern the nurse most?
Correct Answer: C
Rationale: Dexamethasone (Decadron) is a corticosteroid used to reduce inflammation and edema in brain tumors. A client no longer recognizing family members indicates a potential worsening of neurological status, such as increased intracranial pressure or tumor progression, which is a critical concern. Elevated blood glucose and weight gain are common side effects of steroids but are less urgent. Persistent headaches are expected but less concerning than cognitive changes. Therefore, cognitive decline is the most alarming assessment.
Question 3 of 5
A nurse is analyzing the laboratory studies on a client receiving dantrolene sodium (Dantrium). Which of the following laboratory tests would identify an adverse effect associated with the use of the medication?
Correct Answer: C
Rationale: Dantrolene sodium is associated with hepatotoxicity, making liver function tests essential for monitoring adverse effects. Elevated liver enzymes (ALT, AST) may indicate liver damage, requiring discontinuation of the drug. Blood urea nitrogen and creatinine are used to assess kidney function, while triglyceride levels are unrelated to dantrolene's primary adverse effects. Regular monitoring of liver function is critical to ensure patient safety during treatment.
Question 4 of 5
A patient is in an urgent care center and is receiving treatment for mild hyponatremia after spending several hours doing gardening work in the heat of the day. The nurse expects that which drug therapy will be used to treat this condition?
Correct Answer: C
Rationale: In the context of mild hyponatremia, which is a condition where there is a lower-than-normal concentration of sodium in the blood, treatment often involves administering intravenous normal saline infusion administered slowly. This helps to incrementally increase sodium levels in the blood while also ensuring proper hydration. Normal saline is preferred over other fluid solutions as it helps to maintain a stable electrolyte balance. In cases of severe hyponatremia or symptoms like seizures, more aggressive treatment may be necessary, but for mild cases like that described in the scenario, normal saline infusion is typically the appropriate choice.
Question 5 of 5
When the nurse is administering topical nitroglycerin ointment, which technique is correct?
Correct Answer: D
Rationale: The correct technique when administering topical nitroglycerin ointment is to remove the old ointment before applying the new ointment. This is to prevent any potential overdosing of the medication, as nitroglycerin can be rapidly absorbed through the skin. It is important to ensure that the previous application is fully removed before applying a new dose to prevent any accumulation of the medication.
