Nursing Elites

1. A client who is anxious about an impending surgery is at risk for respiratory alkalosis. For which signs and symptoms of respiratory alkalosis does the nurse assess this client?

• A. Disorientation and dyspnea
• B. Drowsiness, headache, and tachypnea
• C. Tachypnea, dizziness, and paresthesias
• D. Dysrhythmias and decreased respiratory rate and depth

Correct answer: C

Rationale: The correct answer is C: Tachypnea, dizziness, and paresthesias. When a client is anxious, they may hyperventilate, leading to respiratory alkalosis. Tachypnea (rapid breathing) is a common sign of respiratory alkalosis. Dizziness and paresthesias (tingling or numbness in the extremities) are also typical symptoms. Choices A, B, and D are incorrect. Disorientation and dyspnea (Choice A) are not specific signs of respiratory alkalosis. Drowsiness, headache, and tachypnea (Choice B) may be more indicative of other conditions. Dysrhythmias and decreased respiratory rate and depth (Choice D) are not consistent with the expected signs of respiratory alkalosis.

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. The healthcare professional is preparing to give a dose of trimethoprim-sulfamethoxazole (TMP-SMX) and learns that the patient takes warfarin (Coumadin). The healthcare professional will request an order for

• A. a decreased dose of TMP-SMX.
• B. a different antibiotic.
• C. an increased dose of warfarin.
• D. coagulation studies.

Correct answer: D

Rationale: Sulfonamides, like trimethoprim-sulfamethoxazole (TMP-SMX), can potentiate the anticoagulant effects of warfarin (Coumadin). To monitor the patient's response and prevent adverse effects, the healthcare professional should request coagulation studies, such as International Normalized Ratio (INR) levels. Choosing a decreased dose of TMP-SMX would not address the potential drug interaction between TMP-SMX and warfarin. Opting for a different antibiotic is not necessary if the interaction can be managed by monitoring. Increasing the dose of warfarin without monitoring could lead to excessive anticoagulation and adverse events, so it's not the appropriate action in this scenario.

4. A nurse is teaching a nursing student how to measure a carotid pulse. The nurse should tell the student to measure the pulse on only one side of the client’s neck primarily because:

• A. It is unnecessary to use both hands
• B. Feeling dual pulsations may lead to an incorrect measurement
• C. Palpating both carotid pulses simultaneously could occlude the trachea
• D. Palpating both carotid pulses simultaneously could cause the heart rate and blood pressure to drop

Correct answer: D

Rationale: The correct answer is D. Applying pressure to both carotid arteries at the same time is contraindicated. Excess pressure to the baroreceptors in the carotid vessels could cause the heart rate and blood pressure to reflexively drop. Palpating both carotid pulses simultaneously could also interfere with the flow of blood to the brain, possibly causing dizziness and syncope. Choices A, B, and C are incorrect. It is necessary to use both hands to measure the carotid pulse accurately. Feeling dual pulsations does not lead to an incorrect measurement, and palpating both carotid pulses simultaneously does not occlude the trachea.

5. A patient taking trimethoprim-sulfamethoxazole (TMP-SMX) to treat a urinary tract infection complains of a sore throat. The nurse will contact the provider to request an order for which laboratory test(s)?

• A. Complete blood count with differential
• B. Throat culture
• C. Urinalysis
• D. Coagulation studies

Correct answer: A

Rationale: When a patient taking trimethoprim-sulfamethoxazole (TMP-SMX) for a urinary tract infection presents with a sore throat, the nurse should request a complete blood count with differential. TMP-SMX can cause life-threatening adverse effects such as agranulocytosis, a condition characterized by a low white blood cell count, which can manifest as a sore throat. Ordering a complete blood count with differential helps assess the patient's white blood cell count to detect any potential serious adverse effects. Throat culture (Choice B) is not indicated unless there are specific signs of a throat infection. Urinalysis (Choice C) is not relevant for assessing a sore throat. Coagulation studies (Choice D) are not typically indicated for a sore throat symptom.
