Nursing Elites

1. A client with a history of atrial fibrillation is admitted with a new onset of confusion. Which laboratory value should the nurse monitor closely?

• A. International Normalized Ratio (INR)
• B. Serum glucose level
• C. White blood cell count
• D. Prothrombin time (PT)

Correct answer: A

Rationale: The correct answer is A: International Normalized Ratio (INR). The INR should be closely monitored in a client with atrial fibrillation to assess the effectiveness and safety of anticoagulation therapy with warfarin. Monitoring the INR helps to ensure that the client is within the therapeutic range to prevent complications such as thrombosis or bleeding. Choices B, C, and D are less relevant in this scenario. While serum glucose levels are important in assessing metabolic status, and white blood cell count and prothrombin time are important indicators for other conditions, they are not the primary focus when a client with atrial fibrillation presents with confusion.

2. A young adult male is admitted to the emergency department with diabetic ketoacidosis (DKA). His pH is 7.25, HCO3 is 12 mEq/L, and blood glucose is 310 mg/dl. Which action should the nurse implement?

• A. Infuse sodium chloride 0.9% (normal saline)
• B. Prepare an emergency dose of glucagon
• C. Determine the last time the client ate
• D. Check urine for ketone bodies with a dipstick

Correct answer: A

Rationale: In DKA, restoring fluid balance with sodium chloride is a priority to address the dehydration and electrolyte imbalances present in this condition. Choice B, preparing an emergency dose of glucagon, is incorrect because DKA is characterized by insulin deficiency, not glucagon deficiency. Choice C, determining the last time the client ate, is not the immediate priority in managing DKA. Choice D, checking urine for ketone bodies with a dipstick, may help confirm the diagnosis of DKA but is not the most critical intervention at this time.

3. A client who is taking an oral dose of a tetracycline complains of gastrointestinal upset. What snack should the nurse instruct the client to take with the tetracycline?

• A. Fruit-flavored yogurt
• B. Cheese and crackers
• C. Cold cereal with skim milk
• D. Toasted wheat bread and jelly

Correct answer: D

Rationale: The correct answer is D: Toasted wheat bread and jelly. Dairy products decrease the effect of tetracycline, so the nurse should instruct the client to avoid them. Toast, which contains no dairy products, may help decrease gastrointestinal symptoms. Choices A, B, and C contain dairy products, which should be avoided when taking tetracycline.

4. The nurse is assessing a client with chronic obstructive pulmonary disease (COPD) who is receiving supplemental oxygen. Which finding requires immediate intervention?

• A. Oxygen saturation of 90%
• B. Respiratory rate of 24 breaths per minute
• C. Use of accessory muscles
• D. Blood pressure of 110/70 mmHg

Correct answer: C

Rationale: The correct answer is C. The use of accessory muscles indicates increased work of breathing and may signal respiratory failure in a client with COPD, requiring immediate intervention. Oxygen saturation of 90% is within an acceptable range for COPD patients on supplemental oxygen. A respiratory rate of 24 breaths per minute is slightly elevated but not an immediate concern. A blood pressure of 110/70 mmHg is within the normal range and does not require immediate intervention in this scenario.

5. While caring for a toddler receiving oxygen (02) via face mask, the nurse observes that the child's lips and nares are dry and cracked. Which intervention should the nurse implement?

• A. Ask the mother what she usually uses on the child's lips and nose.
• B. Apply a petroleum jelly (Vaseline) to the child's nose and lips.
• C. Use a topical lidocaine (Zylocaine viscous) analgesic for cracked lips.
• D. Use a water-soluble lubricant on affected oral and nasal mucosa.

Correct answer: D

Rationale: A water-soluble lubricant is safe to use in conjunction with oxygen therapy, unlike petroleum jelly which is flammable.
