Nursing Elites

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. When caring for a client with a new prescription for enoxaparin for the prevention of DVT, what is an appropriate action by the nurse?

• A. Expel any air bubbles at the top of the prefilled syringe
• B. Massage the injection site to evenly distribute the medication
• C. Inject the medication into the lateral abdominal wall
• D. Administer an NSAID for injection site discomfort

Correct answer: C

Rationale: When administering enoxaparin for the prevention of DVT, the nurse should inject the medication into the lateral abdominal wall. This site is preferred for subcutaneous injections of enoxaparin to reduce the risk of bleeding or injury. Expelling air bubbles, massaging the injection site, or administering an NSAID for discomfort are not appropriate actions and could lead to complications or ineffective medication delivery.

3. A nurse is caring for a client who is 32 weeks pregnant and has cardiac disease. Which of the following positions should the nurse place the client in to promote optimal cardiac output?

• A. Semi-Fowler's
• B. Supine with head elevated
• C. Left lateral
• D. Right lateral

Correct answer: C

Rationale: The correct answer is C: Left lateral. Placing the client in the left lateral position helps promote optimal cardiac output during pregnancy by avoiding pressure on the vena cava. This position improves venous return to the heart and subsequently cardiac output. Option A, Semi-Fowler's position, may not be the best choice for a client with cardiac disease as it does not alleviate pressure on the vena cava. Option B, supine with head elevated, can also compress the vena cava, reducing cardiac output. Option D, right lateral position, does not provide the same benefits as the left lateral position for cardiac output during pregnancy.

4. A healthcare provider is providing dietary teaching to a client who has a new diagnosis of hypertension. Which of the following foods should the provider recommend?

• A. Bananas
• B. Whole grains
• C. Lean beef
• D. Canned soup

Correct answer: C

Rationale: The correct answer is lean beef because it is a good source of protein and essential nutrients. When providing dietary recommendations to clients with hypertension, it is important to focus on lean protein sources to promote a balanced diet. Bananas, although a healthy fruit, may not be the best choice due to their high potassium content, which can sometimes be a concern for individuals with hypertension. Whole grains are generally a good choice, but lean protein like beef is more suitable in this scenario. Canned soup often contains high levels of sodium, which is not recommended for individuals with hypertension.

5. A nurse is teaching a client about the physiological changes that occur with aging. Which of the following findings should the nurse expect?

• A. Decreased sense of taste
• B. Decreased blood pressure
• C. Increased gastric secretions
• D. Increased accommodation to near vision

Correct answer: A

Rationale: The correct answer is A: Decreased sense of taste. As individuals age, they may experience a decrease in their sense of taste due to changes in taste buds and a decrease in saliva production. This can lead to a reduced ability to taste flavors or distinguish between different tastes. Choices B, C, and D are incorrect. Decreased blood pressure is not a consistent physiological change with aging; instead, blood pressure may increase or remain stable. Gastric secretions tend to decrease with age, leading to issues like decreased absorption of certain nutrients. Accommodation to near vision typically decreases with age, causing a condition known as presbyopia, where individuals have difficulty focusing on close objects.
