Nursing Elites

1. A young child admitted to the pediatric unit has fever, irritability, and vomiting with suspected bacterial meningitis. Which cerebrospinal fluid (CSF) result should the nurse anticipate based on these data?

• A. Decreased protein count
• B. Clear, straw-colored fluid
• C. Positive for red blood cells (RBCs)
• D. Decreased glucose level

Correct answer: D

Rationale: In bacterial meningitis, the glucose level in the cerebrospinal fluid (CSF) is typically decreased due to the increased utilization of glucose by the infecting bacteria. This metabolic change leads to a decrease in CSF glucose levels, making choice D the correct answer in this scenario. Choices A, B, and C are incorrect because bacterial meningitis usually results in an increased protein count, cloudy appearance of the CSF due to the presence of bacteria, and absence of red blood cells (RBCs) in the CSF unless there is a traumatic tap, respectively.

2. As a result of opioid administration, a child's respirations are slow and shallow. Which should the nurse anticipate when assessing the child's arterial blood gas?

• A. Increased PCO2 and respiratory acidosis
• B. Decreased PCO2 and respiratory alkalosis
• C. Low pH and low PCO2
• D. High pH and high PCO2

Correct answer: A

Rationale: When a child's respirations are slow and shallow due to opioid administration, it results in hypoventilation. This leads to retaining carbon dioxide, indicated by an increased PCO2 level on arterial blood gas analysis, and subsequently causes respiratory acidosis due to the buildup of CO2 in the blood. Therefore, choice A, 'Increased PCO2 and respiratory acidosis,' is the correct answer. Choices B, C, and D are incorrect because slow and shallow respirations would not lead to decreased PCO2 or respiratory alkalosis (choice B), low pH and low PCO2 (choice C), or high pH and high PCO2 (choice D).

3. What important information should the nurse provide to a patient taking a tetracycline antibiotic?

• A. Take the medication on an empty stomach.
• B. Avoid exposure to sunlight and tanning beds.
• C. Do not take the medication with milk or other dairy products.
• D. The medication may cause permanent staining of your teeth.

Correct answer: D

Rationale: The correct answer is D. Tetracycline antibiotics can bind to calcium in dairy products, decreasing the absorption of the antibiotic. This may result in reduced effectiveness of the medication. Additionally, tetracycline antibiotics can cause permanent staining of teeth, especially in children below 8 years of age and in pregnant women. Therefore, it is crucial for the patient to be aware of this potential side effect and to discuss any concerns with their healthcare provider. Choices A, B, and C are incorrect because tetracycline antibiotics should be taken with food to reduce gastrointestinal upset, exposure to sunlight is not a significant concern with tetracycline antibiotics, and the issue with dairy products is related to calcium binding and reduced absorption rather than an issue of empty stomach intake.

4. What is the next food texture after 'soft and bite-sized pieces of meltable and soft-solid foods'?

• A. Regular
• B. Liquidized
• C. Pur�ed
• D. Minced and Moist

Correct answer: A

Rationale: After mastering soft and bite-sized pieces, children typically progress to regular table foods.

5. The renin-angiotensin-aldosterone system plays an important role in maintaining blood pressure. Which compound in this system is most powerful at raising blood pressure?

• A. Angiotensin I
• B. Angiotensin II
• C. Angiotensin III
• D. Renin

Correct answer: B

Rationale: Angiotensin II is the most potent compound in the renin-angiotensin-aldosterone system for raising blood pressure. It acts as a powerful vasoconstrictor, leading to increased systemic vascular resistance. Angiotensin II is formed from angiotensin I through the action of the angiotensin-converting enzyme. While renin initiates the cascade by converting angiotensinogen to angiotensin I, it is angiotensin II that exerts the strongest pressor effect.
