Nursing Elites

1. The nurse asks a client who is about to have a cardiac catheterization about any allergies. The client states, 'I always get a rash when I eat shellfish.' Which of the following is the priority nursing action?

• A. Attach a wristband indicating the client's allergy
• B. Ask the client if any other foods cause such a reaction
• C. Notify the dietary department of the client's allergy
• D. Notify the provider of the client's allergy

Correct answer: D

Rationale: Notifying the provider of the client's shellfish allergy is crucial to prevent a potential reaction from the contrast dye. While attaching a wristband indicating the allergy may be necessary, the priority is to inform the provider. Asking the client about other foods causing a similar reaction or notifying the dietary department, although important, are not the priority in this situation.

2. A client is prescribed 1g of potassium phosphate IV to be infused continuously over 6 hr. Available is 1 g in 250 ml of dextrose 5%. What rate should the nurse set the IV pump to run at?

• A. 40 ml/hr
• B. 42 ml/hr
• C. 44 ml/hr
• D. 46 ml/hr

Correct answer: B

Rationale: To calculate the IV rate, divide the total volume by the total time in hours. In this case, 1 g in 250 ml is to be infused over 6 hours. Therefore, 250 ml / 6 hr = 42 ml/hr. This means the IV pump should be set to run at 42 ml/hr. Choices A, C, and D are incorrect as they do not accurately calculate the infusion rate based on the provided information.

3. When is removal of the restraints by the nurse appropriate?

• A. When medication that has been administered has taken effect
• B. When no acts of aggression are observed in the hour following the release of two extremity restraints
• C. When the nurse explores with the client the reasons for the angry and aggressive behavior
• D. When the client apologizes and tells the nurse that it will never happen again

Correct answer: B

Rationale: The correct answer is B. The nurse can safely remove restraints once no aggressive behavior is observed after releasing two extremity restraints for an hour. Choice A is incorrect because the removal of restraints should be based on the client's behavior rather than just the effect of medication. Choice C is incorrect as exploring reasons for aggressive behavior should be done before or during the intervention, not as a condition for removing restraints. Choice D is incorrect since an apology from the client does not guarantee a change in behavior or indicate that it is safe to remove the restraints.

4. What are the clinical manifestations of left-sided heart failure, and how do they differ from right-sided heart failure?

• A. Jugular venous distention and hepatojugular reflex
• B. Hepatomegaly, ascites, and peripheral edema
• C. Dyspnea, cough, and orthopnea
• D. Pulmonary congestion and fatigue

Correct answer: A

Rationale: The correct answer is A. Clinical manifestations of left-sided heart failure include pulmonary symptoms such as dyspnea, cough, and orthopnea. However, left-sided heart failure can also manifest as jugular venous distention and hepatojugular reflex due to the backflow of blood into the pulmonary circulation. Right-sided heart failure is characterized by systemic symptoms like hepatomegaly, ascites, and peripheral edema. Choice B is incorrect as it presents manifestations of right-sided heart failure. Choice C includes symptoms of left-sided heart failure. Choice D describes pulmonary congestion, which is more specific to left-sided heart failure, but it does not encompass the full range of clinical manifestations for left-sided heart failure.

5. A healthcare provider is assessing a patient with dehydration. Which finding indicates the patient's condition is worsening?

• A. Dry mucous membranes.
• B. Tachycardia and low blood pressure.
• C. Bradycardia and shallow respirations.
• D. Clear lung sounds.

Correct answer: B

Rationale: Tachycardia and low blood pressure are indicative of worsening dehydration in a patient. Tachycardia is the body's compensatory mechanism to maintain cardiac output in response to decreased intravascular volume, while low blood pressure reflects inadequate perfusion due to decreased fluid levels. Bradycardia and shallow respirations are not typical findings in worsening dehydration, and clear lung sounds do not directly correlate with the severity of dehydration.
