Nursing Elites

1. A client has an elevated blood urea nitrogen (BUN)/creatinine ratio. Which action should the nurse take first?

• A. Assess the client’s dietary habits.
• B. Inquire about the client's use of nonsteroidal anti-inflammatory drugs (NSAIDs).
• C. Hold the client’s metformin (Glucophage).
• D. Contact the health care provider immediately.

Correct answer: A

Rationale: An elevated blood urea nitrogen (BUN)/creatinine ratio can indicate various conditions such as dehydration, urinary obstruction, catabolism, or a high-protein diet. The initial action the nurse should take is to assess the client’s dietary habits to determine if the elevated ratio is related to diet. Inquiring about the use of NSAIDs is important as they can impact kidney function, but dietary causes should be ruled out first. Holding metformin or contacting the health care provider without assessing the dietary habits would be premature actions as they may not address the underlying cause of the elevated BUN/creatinine ratio.

2. What do crackles heard on lung auscultation indicate?

• A. Cyanosis.
• B. Bronchospasm.
• C. Airway narrowing.
• D. Fluid-filled alveoli.

Correct answer: D

Rationale: Crackles heard on lung auscultation are caused by the popping open of small airways that are filled with fluid. This is commonly associated with conditions such as pulmonary edema, pneumonia, or heart failure. Cyanosis (Choice A) is a bluish discoloration of the skin and mucous membranes due to low oxygen levels in the blood, not directly related to crackles. Bronchospasm (Choice B) refers to the constriction of the airway smooth muscle, causing difficulty in breathing but does not typically produce crackles. Airway narrowing (Choice C) can lead to wheezing but is not directly linked to crackles heard on auscultation.

3. Upon admission, a 77-year-old female client presents with confusion, loss of appetite, nausea, vomiting, and headache, with a pulse rate of 43 beats per minute. Which question should the nurse prioritize asking the client or her family?

• A. Does the client have her own teeth or dentures?
• B. Does the client take aspirin, and if so, what is the dosage?
• C. Does the client take nitroglycerin?
• D. Does the client take digitalis?

Correct answer: D

Rationale: The correct answer is D. The client's symptoms suggest digitalis toxicity, a potentially life-threatening condition that requires immediate attention. Digitalis toxicity can present with symptoms such as anorexia, nausea, vomiting, headache, and bradycardia (low pulse rate). Given the client's presentation, it is crucial to assess for digitalis use as elderly individuals are more susceptible to this type of intoxication. Choices A, B, and C are important aspects to consider during the assessment, but in this scenario, the priority lies in identifying and addressing the potential digitalis toxicity due to the severity of symptoms and the need for prompt intervention.

4. Which of the following medications is commonly prescribed for hypertension?

• A. Atenolol
• B. Aspirin
• C. Ibuprofen
• D. Metformin

Correct answer: A

Rationale: The correct answer is Atenolol. Atenolol is a beta-blocker commonly prescribed to manage hypertension due to its ability to reduce the heart rate and lower blood pressure. Options B, C, and D are incorrect because aspirin, ibuprofen, and metformin are not typically used as first-line treatments for hypertension. Aspirin is more commonly used for its antiplatelet effects, ibuprofen is a nonsteroidal anti-inflammatory drug, and metformin is primarily used for managing diabetes.

5. A patient is being treated for shock after a motor vehicle accident. The provider orders 6% dextran 75 to be given intravenously. The nurse should expect which outcome as the result of this infusion?

• A. Decreased urine output
• B. Improved blood oxygenation
• C. Increased interstitial fluid
• D. Stabilization of heart rate and blood pressure

Correct answer: D

Rationale: 6% Dextran 75 is a high molecular-weight colloidal solution used to treat shock from burns or trauma. Colloids like 6% dextran 75 are plasma expanders that help increase blood volume, leading to improved heart rate and blood pressure stabilization. The infusion of plasma expanders does not typically decrease urine output. It primarily aims to stabilize circulation rather than affect blood oxygenation or increase interstitial fluid levels.
