1. A nurse is preparing to administer dopamine hydrochloride at 4 mcg/kg/min for a client weighing 80 kg. How many mL/hr should the nurse set the IV infusion to deliver?
- A. 6 mL/hr
- B. 8 mL/hr
- C. 12 mL/hr
- D. 16 mL/hr
Correct answer: A
Rationale: To calculate the correct rate, you first need to convert the weight to micrograms: 4 mcg/kg/min * 80 kg = 320 mcg/min. Then, convert micrograms to milligrams: 320 mcg/min / 1000 = 0.32 mg/min. Next, calculate how many milligrams per hour: 0.32 mg/min * 60 min/hr = 19.2 mg/hr. Finally, determine the mL/hr rate by using the concentration provided: 19.2 mg/hr / 800 mg in 250 mL = 6 mL/hr. Therefore, the correct answer is 6 mL/hr. Choice B, 8 mL/hr, is incorrect as it does not reflect the accurate calculation based on the weight and drug concentration. Choices C and D, 12 mL/hr and 16 mL/hr, are also incorrect as they do not align with the correct calculation of the infusion rate for dopamine hydrochloride based on the client's weight and the medication concentration.
2. A nurse is assessing a client who has a stage III pressure ulcer that is healing poorly. The nurse should identify that which of the following vitamin deficiencies increases the client’s risk for delayed wound healing?
- A. Vitamin C
- B. Vitamin D
- C. Vitamin E
- D. Vitamin B6
Correct answer: A
Rationale: Vitamin C deficiency can impair collagen synthesis and delay wound healing, making it important for recovery from pressure ulcers.
3. Before administering lithium to a client with bipolar disorder who has been taking the medication for 1 year, the nurse should check to see that which of the following tests has been completed?
- A. Thyroid hormone assay
- B. Liver function tests
- C. Erythrocyte sedimentation rate
- D. Brain natriuretic peptide
Correct answer: A
Rationale: The correct answer is to check the thyroid hormone assay. Long-term lithium use can result in thyroid dysfunction, making it crucial to monitor the client's thyroid function regularly to detect any abnormalities early and prevent potential complications. Liver function tests (choice B) are not specifically associated with lithium therapy. Erythrocyte sedimentation rate (choice C) is a nonspecific test for inflammation and not directly related to lithium therapy. Brain natriuretic peptide (choice D) is a test used to diagnose heart failure and is not relevant to monitoring lithium therapy.
4. Which valve opens during ventricular systole and closes during ventricular diastole?
- A. Aortic valve
- B. Pulmonary valve
- C. Mitral valve
- D. Tricuspid valve
Correct answer: B
Rationale: The correct answer is B: Pulmonary valve. The pulmonary valve opens during ventricular systole to allow blood to flow from the right ventricle into the pulmonary artery. The aortic valve opens during ventricular systole to allow blood to flow from the left ventricle into the aorta. The mitral valve and tricuspid valve are atrioventricular valves that open during ventricular diastole to allow blood to flow from the atria into the ventricles.
5. What is the treatment for patients with hemophilia A?
- A. Chemotherapy
- B. Factor VIII replacement
- C. Heparin administration
- D. Bone marrow transplant
Correct answer: B
Rationale: The correct treatment for patients with hemophilia A is Factor VIII replacement. Hemophilia A is a genetic disorder where there is a deficiency in clotting factor VIII. Therefore, replacing this factor is crucial in managing and preventing bleeding episodes. Choice A, chemotherapy, is not the correct treatment for hemophilia A. Choice C, heparin administration, is not recommended as it can further increase the risk of bleeding in patients with hemophilia. Choice D, bone marrow transplant, is not a standard treatment for hemophilia A.
