Nursing Elites

1. Which condition can result from prolonged vomiting or diarrhea?

• A. Intracellular fluid
• B. Interstitial fluid
• C. Dehydration
• D. Electrolyte

Correct answer: C

Rationale: The correct answer is C: Dehydration. Prolonged vomiting or diarrhea can lead to significant fluid loss, causing dehydration. Intracellular fluid (choice A) and interstitial fluid (choice B) refer to specific compartments of body fluid and are not conditions resulting from vomiting or diarrhea. Electrolytes (choice D) are minerals that help maintain fluid balance in the body but are not the condition directly resulting from prolonged vomiting or diarrhea.

2. The ICU nurse is caring for a patient who experienced trauma in a workplace accident. The patient is complaining of having trouble breathing with abdominal pain. An ABG reveals the following results: pH 7.28, PaCO2 50 mm Hg, HCO3 23 mEq/L. The nurse should recognize the likelihood of what acidbase disorder?

• A. Respiratory acidosis
• B. Metabolic alkalosis
• C. Respiratory alkalosis
• D. Mixed acidbase disorder

Correct answer: D

Rationale:

3. The renin and angiotensin systems help to maintain the balance of sodium and water in the body. What other functions do these systems serve?

• A. Regulating hemoglobin levels
• B. Maintaining a healthy blood volume
• C. Releasing platelets when tissues are injured
• D. Lowering blood volumes

Correct answer: B

Rationale: The correct answer is B: Maintaining a healthy blood volume. The renin and angiotensin systems not only help to regulate sodium and water balance in the body but also play a crucial role in maintaining an adequate blood volume. This is essential for normal blood pressure regulation and overall cardiovascular health. Choices A, C, and D are incorrect because hemoglobin levels are primarily regulated by the bone marrow and erythropoietin, platelets are released in response to blood vessel injury by a different mechanism, and the systems do not focus on lowering blood volumes but rather on maintaining them.

4. You are the nurse evaluating a newly admitted patients laboratory results, which include several values that are outside of reference ranges. Which of the following would cause the release of antidiuretic hormone (ADH)?

• A. Increased serum sodium
• B. Decreased serum potassium
• C. Decreased hemoglobin
• D. Increased platelets

Correct answer: A

Rationale:

5. A nurse preparing to start an IV on a newly admitted patient teaches the patient about the procedure and begins to prepare the site. The nurse should always start by:

• A. Leaving one hand ungloved to assess the site
• B. Preparing the skin with an iodine solution
• C. Asking the patient if they are allergic to latex or iodine
• D. Removing excessive hair at the selected site

Correct answer: C

Rationale: Before preparing the skin, the nurse should ask the patient if they are allergic to latex or iodine, which are commonly used in IV therapy setup. This is crucial to prevent potential allergic reactions at the IV site or even life-threatening anaphylaxis. Leaving one hand ungloved (choice A) is not a recommended practice as both hands should be gloved for infection control. While preparing the skin with an iodine solution (choice B) is a step in the process, ensuring the patient's safety by checking for allergies comes first. Removing excessive hair at the selected site (choice D) is not necessary and can lead to skin irritation.
