Nursing Elites

1. A client is scheduled for an abdominal ultrasound in the morning and has been instructed to fast overnight. The client asks the nurse why fasting is necessary. What is the best response?

• A. It helps reduce the production of intestinal gases.
• B. It ensures clearer imaging by emptying the stomach.
• C. It prevents the risk of aspiration during the procedure.
• D. It is a standard procedure for all surgical interventions.

Correct answer: B

Rationale: The correct answer is B: 'It ensures clearer imaging by emptying the stomach.' Fasting before an abdominal ultrasound is essential to empty the stomach, allowing for better visualization of the abdominal organs. This improves the quality of the imaging and enhances diagnostic accuracy. Choices A, C, and D are incorrect because reducing intestinal gases, preventing aspiration, and being a standard procedure for surgical interventions are not the primary reasons for fasting before an abdominal ultrasound.

2. A client with a severe peanut allergy accidentally ingested peanut-containing food and is experiencing anaphylaxis. What is the nurse's priority action?

• A. Administer an epinephrine injection
• B. Call for immediate medical help
• C. Monitor airway, breathing, and circulation
• D. All of the above

Correct answer: A

Rationale: The priority action for a client experiencing anaphylaxis due to a severe peanut allergy is to administer an epinephrine injection. Epinephrine is the first-line treatment for anaphylaxis as it can rapidly reverse the severe allergic reaction. While calling for immediate medical help is important, administering epinephrine takes precedence because it can be life-saving in this situation. Monitoring airway, breathing, and circulation is essential in managing anaphylaxis, but administering epinephrine is the priority action to halt the progression of the allergic reaction and stabilize the client's condition. Therefore, 'Administer an epinephrine injection' is the most critical initial intervention.

3. The client with high blood pressure is being taught by the nurse to avoid adding salt during cooking. What effect does sodium have on blood pressure?

• A. It decreases the viscosity of blood
• B. It leads to increased fluid retention
• C. It causes vasoconstriction of the blood vessels
• D. It enhances the excretion of potassium

Correct answer: C

Rationale: The correct answer is C: 'It causes vasoconstriction of the blood vessels.' Sodium can lead to vasoconstriction, which narrows the blood vessels, increasing resistance to blood flow and subsequently raising blood pressure. Choices A, B, and D are incorrect. Sodium does not decrease blood viscosity, but it can lead to fluid retention, which increases blood volume and pressure. It does not enhance the excretion of potassium; instead, high sodium intake can lead to potassium excretion by the kidneys.

4. The nurse is monitoring a client with an IV infusion in the left antecubital fossa. The site is warm, red, and without swelling. What conclusion should the nurse draw from these findings?

• A. The IV fluids are infusing into the subcutaneous tissues
• B. The infusion pump is functioning properly
• C. The insertion date should be verified and the IV discontinued
• D. The site is inflamed and should be reported

Correct answer: B

Rationale: The correct answer is B. Warmth and redness at the IV site without swelling indicate a localized reaction, which is common and does not necessarily indicate infiltration of IV fluids into the subcutaneous tissues. The absence of swelling suggests that the IV is correctly placed. Therefore, the nurse should conclude that the infusion pump is functioning properly. Choice A is incorrect as warmth and redness alone do not indicate subcutaneous infiltration. Choice C is incorrect as discontinuing the IV solely based on warmth and redness without swelling is not necessary. Choice D is incorrect as the absence of swelling signifies a localized reaction rather than inflammation requiring immediate reporting.

5. A new father asks the nurse the reason for placing an ophthalmic ointment in his newborn's eyes. What information should the nurse provide?

• A. Possible exposure to an environmental staphylococcus infection can infect the newborn's eyes and cause visual deficits
• B. The newborn is at risk for blindness from a corneal syphilitic infection acquired from a mother's infected vagina
• C. Treatment prevents tear duct obstruction with harmful exudate from a vaginal birth that can lead to dry eyes in the newborn
• D. State law mandates all newborns receive prophylactic treatment to prevent gonorrheal or chlamydial ophthalmic infection

Correct answer: D

Rationale: The correct answer is D because informing about state law emphasizes the legal requirement and public health rationale behind prophylactic eye treatment to prevent serious infections like gonorrheal or chlamydial ophthalmic infection. Choices A, B, and C are incorrect. Choice A focuses on staphylococcus infection, which is not the primary concern addressed by the prophylactic ointment. Choice B mentions a specific infection acquired from the mother's infected vagina, which is not the main reason for the ophthalmic ointment. Choice C discusses tear duct obstruction and dry eyes, which are not the primary concerns addressed by the prophylactic ointment.
