NurseDive Free Nursing Practice Question
A client who weighs 176 pounds receives a prescription for norepinephrine 2 mcg/min intravenously (IV). The IV bag is labeled, "Norepinephrine 4 mg in dextrose 5% in water (D;W) 1,000 mL." How many mL/hour should the nurse program the infusion pump? (Enter numerical value only.).

Full Explanation
The correct answer is 30 mL/hour.
Step 1 is to calculate the total amount of norepinephrine in the IV bag: 4 mg norepinephrine ÷ 1000 mL = 0.004 mg/mL
Step 2 is to convert the patient's weight from pounds to kilograms: 176 pounds ÷ 2.2 = 80 kilograms
Step 3 is to calculate the total amount of norepinephrine the patient will receive per minute: 2 mcg/min × 60 min = 120 mcg/min
Step 4 is to convert micrograms (mcg) to milligrams (mg): 120 mcg ÷ 1000 = 0.12 mg
Step 5 is to calculate the total volume of norepinephrine needed per hour: 0.12 mg ÷ 0.004 mg/mL = 30 mL/hour
Therefore, the nurse should program the infusion pump to deliver 30 mL/hour.

A client is admitted to the intensive care unit with diabetes insipidus due to a pituitary gland tumor.
Which potential complication should the nurse monitor closely?
A. Ketonuria.
Ketonuria is not a common complication of diabetes insipidus. Ketonuria is associated with diabetes mellitus, a different condition that results in the accumulation of ketones in the urine due to insufficient insulin.
B. Peripheral edema.
Peripheral edema is also an unlikely complication of diabetes insipidus. Diabetes insipidus is characterized by excessive thirst and urination, not fluid retention or peripheral edema.
C. Hypokalemia.
D. Elevated blood pressure.

The nurse is caring for a client with the sexually transmitted infection (STI) syphilis.
The client reports having unprotected sex.
Which response should the nurse provide?
A. Emphasize that using safe sex practices removes the risk of STIs.
Emphasize that using safe sex practices removes the risk of STIs. Rationale: While promoting safe sex practices is essential in preventing STIs, this response is not directly addressing the client's situation. The client already reports having unprotected sex, so this choice does not provide relevant information or address the potential consequences.
B. Explain that reinfections occur from sex with untreated partners.
Explain that reinfections occur from sex with untreated partners. Rationale: This is the correct response. Syphilis is a sexually transmitted infection that can be treated with antibiotics, but reinfections can occur if sexual partners are not treated. This response provides essential information about the potential consequences of unprotected sex with untreated partners.
C. Clarify that all STIs are transmitted through sexual intercourse.
Clarify that all STIs are transmitted through sexual intercourse. Rationale: While this statement is accurate in a general sense, it does not specifically address the client's situation or the risks associated with syphilis. It lacks the focus needed to educate the client effectively about their current situation.
D. Provide counseling that most contraceptives protect against infection.
Provide counseling that most contraceptives protect against infection. Rationale: This response is inaccurate. Contraceptives primarily aim to prevent pregnancy, not protect against STIs. Therefore, it does not address the client's concern or provide relevant information about syphilis.

When conducting diet teaching for a client who was diagnosed with hypertension, which food(s) should the nurse encourage the client to eat? (Select all that apply.).
A. Fresh or frozen vegetables without sauce.
Fresh or frozen vegetables without sauce. Rationale: Fresh or frozen vegetables without sauce are excellent choices for a client with hypertension. These foods are low in sodium and can help manage blood pressure effectively. The absence of added sauces ensures that there is no hidden sodium content.
B. Fruits without sauce.
Fruits without sauce. Rationale: Fruits without sauce are also suitable for clients with hypertension. They are naturally low in sodium and provide essential nutrients that can support blood pressure control. The absence of sauce ensures that no additional sodium is added.
C. Pickled olives.
Pickled olives. Rationale: Pickled olives are high in sodium due to the pickling process. Therefore, they are not recommended for clients with hypertension as they can lead to an increase in blood pressure.
D. Canned soup.
Canned soup. Rationale: Canned soup often contains high levels of sodium, which is not suitable for clients with hypertension. Excessive sodium intake can contribute to elevated blood pressure and should be avoided.
E. Cottage cheese.
