A patient has been admitted with a fever of 102.8 F (39.3 C), with an unknown origin.

The patient’s urine is cloudy, foul-smelling, and dark amber.

Orders have been given to obtain urine and blood cultures immediately and to administer an antibiotic intravenously.

In what order should the nurse complete these orders?

Administer the antibiotic dose, then obtain blood and urine cultures.

Obtain urine culture, administer the antibiotic dose, then obtain blood culture.

Obtain blood culture, administer the antibiotic dose, then obtain urine culture.

Obtain blood and urine cultures, then administer the antibiotic dose.

Answer and Explanation

The Correct Answer is D

Choice A rationale:

Administering the antibiotic dose before obtaining the cultures could potentially affect the results of the cultures. Antibiotics are designed to kill or inhibit the growth of bacteria, so administering them before obtaining the cultures could lead to false negatives. This could lead to incorrect or delayed diagnosis and treatment.

Choice B rationale:

While obtaining the urine culture before administering the antibiotic dose is a good step, it should not be done before obtaining the blood culture. Blood cultures are usually obtained before urine cultures because they can help identify bacteria or fungi in the blood. This can be crucial in diagnosing conditions like sepsis. Furthermore, administering the antibiotic dose before obtaining the blood culture could affect the results of the culture.

Choice C rationale:

Obtaining the blood culture before administering the antibiotic dose is a good step, but the urine culture should also be obtained before the antibiotic dose is administered. Administering the antibiotic dose before obtaining all necessary cultures could affect the results of the cultures and lead to incorrect or delayed diagnosis and treatment.

Choice D rationale:

This is the correct sequence of actions. The nurse should first obtain both blood and urine cultures before administering the antibiotic dose. This is because the antibiotic could potentially kill or inhibit the growth of bacteria, which could affect the results of the cultures. By obtaining the cultures first, the healthcare team can ensure they are getting accurate results that have not been influenced by the antibiotics. This can lead to a more accurate diagnosis and more effective treatment plan.

Correct Answer is D

Explanation

Choice A rationale:

Choice B rationale:

Choice C rationale:

Choice D rationale:

A. Polyuria B. Sweating C. Tachycardia D. Blurry vision

Correct Answer is ["B","C","D"]

Explanation

Choice A rationale:

Polyuria, which is frequent or excessive urination, is not typically a symptom of hypoglycemia. It is more commonly associated with hyperglycemia, or high blood sugar levels.

Choice B rationale:

Sweating is indeed a common symptom of hypoglycemia. When blood sugar levels fall too low, the body may respond by sweating as it releases adrenaline in response to the hypoglycemic state.

Choice C rationale:

Tachycardia, or a fast heartbeat, is another common symptom of hypoglycemia. This is part of the body’s response to low blood sugar levels, as it releases adrenaline to try to raise these levels.

Choice D rationale:

Blurry vision can be a symptom of hypoglycemia. When blood sugar levels fall, it can affect the ability of the eyes to focus, leading to blurry vision.

Choice E rationale:

Polydipsia, or excessive thirst, is not typically a symptom of hypoglycemia. Like polyuria, it is more commonly associated with hyperglycemia.
