Nursing Elites

1. The healthcare provider prescribes diagnostic tests for a client with pneumonia identified on a chest X-ray. Which diagnostic test should the nurse review for implementation to guide the most therapeutic treatment of pneumonia?

• A. Sputum culture and sensitivity
• B. Blood cultures
• C. Arterial blood gases (ABG)
• D. Computerized tomography (CT) of the chest

Correct answer: A

Rationale: Sputum culture and sensitivity is the most appropriate diagnostic test for pneumonia as it helps in identifying the causative organism, which is crucial for guiding the selection of the most effective antibiotic therapy. Blood cultures (choice B) are more useful in identifying systemic infections rather than pneumonia specifically. Arterial blood gases (ABG) (choice C) are helpful in assessing oxygenation but do not directly aid in identifying the causative organism. Computerized tomography (CT) of the chest (choice D) is useful for evaluating structural abnormalities in the lungs but is not the initial test of choice for diagnosing pneumonia.

2. In a patient with asthma, which of the following is the most important indicator of respiratory function?

• A. Oxygen saturation.
• B. Respiratory rate.
• C. Arterial blood gases.
• D. Peak expiratory flow rate.

Correct answer: D

Rationale: The peak expiratory flow rate is the most important indicator of respiratory function in asthma because it measures how quickly air can be exhaled, reflecting the severity of airflow limitation. Oxygen saturation (Choice A) is important in assessing oxygenation, but it does not directly reflect respiratory function. Respiratory rate (Choice B) can provide information on breathing patterns but does not quantify airflow limitation. Arterial blood gases (Choice C) give information about gas exchange but are not as specific for assessing asthma control and severity as peak expiratory flow rate.

3. A healthcare professional reviews the allergy list of a client scheduled for an intravenous urography. Which client allergy should prompt urgent contact with the healthcare provider?

• A. Seafood
• B. Penicillin
• C. Bee stings
• D. Red food dye

Correct answer: A

Rationale: Clients with seafood allergies should alert healthcare professionals to urgently contact the healthcare provider before an intravenous urography. The standard dyes used in this procedure can trigger severe allergic reactions in individuals with seafood allergies. Penicillin, bee stings, and red food dye allergies do not pose a direct threat during intravenous urography, making them less critical for immediate intervention.

4. The nurse assesses a client who is newly diagnosed with hyperthyroidism and observes that the client's eyeballs are protuberant, causing a wide-eyed appearance and eye discomfort. Based on this finding, which action should the nurse include in the client's plan of care?

• A. Assess for signs of increased intracranial pressure
• B. Prepare to administer intravenous levothyroxine
• C. Review the client's serum electrolyte values
• D. Obtain a prescription for artificial tear drops

Correct answer: D

Rationale: In hyperthyroidism, eye discomfort due to protuberant eyeballs (exophthalmos) can be alleviated by using artificial tear drops. These drops help prevent complications associated with dry eyes and promote comfort. Assessing for signs of increased intracranial pressure (Choice A) is not directly related to the client's eye discomfort from hyperthyroidism. Administering intravenous levothyroxine (Choice B) is not the appropriate intervention for managing eye discomfort in hyperthyroidism. Reviewing serum electrolyte values (Choice C) is important in hyperthyroidism but is not directly addressing the client's current eye discomfort and protuberant eyeballs.

5. In a client with congestive heart failure, the nurse would be correct in withholding a dose of digoxin without specific instruction from the healthcare provider if the client's

• A. serum digoxin level is 1.5 ng/mL.
• B. blood pressure is 104/68 mmHg.
• C. serum potassium level is 3 mEq/L.
• D. apical pulse is 68/min.

Correct answer: C

Rationale: The correct answer is C. Hypokalemia can precipitate digitalis toxicity in individuals on digoxin, increasing the risk of dangerous dysrhythmias. A serum potassium level of 3 mEq/L is below the normal range (3.5 to 5.5 mEq/L) and indicates hypokalemia, which can potentiate the effects of digoxin. Choices A, B, and D are not directly related to the potential for digitalis toxicity. Serum digoxin level of 1.5 ng/mL is within the therapeutic range, blood pressure of 104/68 mmHg is not a contraindication for administering digoxin, and an apical pulse of 68/min is within the normal range and not a reason to withhold digoxin.
