Question 1 of 5
What role do the kidneys have in the pharmacokinetics process?
Correct Answer: A
Rationale: The correct answer is A: Excretion. The kidneys play a crucial role in pharmacokinetics by filtering drugs and their metabolites from the bloodstream and eliminating them through urine. This process helps maintain drug concentration levels in the body and prevent toxicity. Other choices are incorrect because: B: Absorption occurs in the gastrointestinal tract, C: Metabolism mainly takes place in the liver, and D: Distribution involves the transport of drugs throughout the body via the bloodstream.
Therefore, A is the correct answer as it specifically pertains to the elimination of drugs from the body.
Question 2 of 5
A resident of a long-term care facility receives 12.5 mg metoprolol (Lopressor) at 8 AM and 8 PM daily. Before administering this drug, the nurse should perform and document what assessment findings?
Correct Answer: B
Rationale: The correct answer is B: Heart rate and blood pressure. Before administering metoprolol, a beta-blocker medication that affects the heart, it is crucial to assess the resident's heart rate and blood pressure to ensure they are within the safe parameters for administering the medication. Monitoring these vital signs helps prevent potential adverse effects such as bradycardia or hypotension. Assessing temperature and respiratory rate (
Choice
A) may be important for other medications but are not specifically required for metoprolol. Level of consciousness and pain level (
Choice
C) are important assessments but are not directly related to the medication's action. Oxygen saturation and respiratory rate (
Choice
D) are also important but are not the primary assessments needed before administering metoprolol.
Question 3 of 5
A nurse is teaching a class about pulmonary circulation. The nurse should include that blood flows from the heart to the lungs from the right ventricle starting from which of the following locations?
Correct Answer: A
Rationale: The correct answer is A: Pulmonary artery. The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs for oxygenation. This is the first step in the pulmonary circulation process. The blood then returns to the heart through the pulmonary veins, carrying oxygenated blood to the left atrium. Left ventricle pumps this oxygenated blood to the rest of the body.
Choices B, C, and D are incorrect as they do not align with the direction of blood flow in the pulmonary circulation system.
Question 4 of 5
A nurse is teaching a client who has a new prescription for docusate. Which of the following information should the nurse include in the teaching?
Correct Answer: A
Rationale:
Correct Answer: A
Rationale: Taking docusate with a full glass of water helps prevent dehydration and ensures the medication works effectively by softening the stool. This action helps prevent constipation.
Summary:
B: Taking docusate on an empty stomach is not necessary for its effectiveness.
C: Taking docusate before bedtime may be beneficial for some individuals based on their bowel habits.
D: Abdominal pain is not a common side effect of docusate and should not be expected.
Question 5 of 5
A nurse is preparing to instill 840 mL of enteral nutrition via a client's gastrostomy tube over 24 hr using an infusion pump. The nurse should set the infusion pump to deliver how many mL/hr?
Correct Answer: A
Rationale: The correct answer is A: 35 mL/hr.
To calculate the rate, divide the total volume by the total time: 840 mL ÷ 24 hr = 35 mL/hr. This ensures a consistent and appropriate flow of enteral nutrition. Incorrect choices (B-G) would not provide the accurate rate needed for the prescribed amount over the specified time frame.
