Nursing Elites

1. Signs and symptoms of stroke may include all of the following EXCEPT:

• A. Sudden weakness or numbness of the face, arm, or leg.
• B. Sudden confusion.
• C. Sudden headache with no known cause.
• D. Hypotension.

Correct answer: D

Rationale: Hypotension is not a typical sign or symptom of an acute stroke. The correct signs and symptoms of a stroke include sudden weakness or numbness of the face, arm, or leg, sudden confusion, and a sudden headache with no known cause. Hypotension, which refers to low blood pressure, is not a common indicator of a stroke. It is important to differentiate between hypotension and hypertension in the context of stroke symptoms, as hypertension (high blood pressure) is actually a risk factor for strokes. Sudden weakness, numbness, confusion, and headache are signs associated with a stroke due to a disruption in blood flow to the brain. Hypotension, on the other hand, primarily indicates low blood pressure and is not directly linked to the typical presentation of a stroke.

2. A patient with severe mitral regurgitation and decreased cardiac output is being cared for by a nurse. The nurse assesses the patient for mental status changes. What is the rationale for this intervention?

• A. Decreased cardiac output can cause hypoxia to the brain
• B. Mental status changes may be a side effect of the patient's medication
• C. Mitral regurgitation is a complication associated with some neurological disorders
• D. The patient may be confused about his diagnosis

Correct answer: A

Rationale: When caring for a patient with severe mitral regurgitation and decreased cardiac output, assessing for mental status changes is crucial. Decreased cardiac output can lead to inadequate perfusion and oxygenation of vital organs, including the brain, resulting in hypoxia. This hypoxia can manifest as mental status changes such as confusion, restlessness, or lethargy. Therefore, monitoring mental status helps in identifying potential hypoxic states and guiding appropriate interventions. The other options are incorrect as they do not directly correlate decreased cardiac output with potential hypoxia-induced mental status changes.

3. A patient with right lower-lobe pneumonia has been treated with IV antibiotics for 3 days. Which assessment data obtained by the nurse indicates that the treatment has been effective?

• A. Bronchial breath sounds are heard at the right base.
• B. The patient coughs up small amounts of green mucus.
• C. The patients white blood cell (WBC) count is 9000/L
• D. Increased tactile fremitus is palpable over the right chest

Correct answer: C

Rationale: The normal WBC count indicates that the antibiotics have been effective. All the other data suggest that a change in treatment is needed.

4. The healthcare professional calculates the IV flow rate for a patient receiving an antibiotic. The patient is to receive 100mL of the antibiotic over 30 minutes. The IV infusion set has a drop factor of 10 drops per milliliter. How many drops per minute should the healthcare professional set the IV to deliver?

• A. 11
• B. 19
• C. 26
• D. 33

Correct answer: D

Rationale: To determine the drops per minute for the IV flow rate, you can use the formula: Drops Per Minute = (Milliliters to be infused x Drop Factor) / Time in Minutes. Substituting the given values, you get 100 mL x 10 drops/mL / 30 minutes = 33 drops per minute. Therefore, the correct answer is 33, as the healthcare professional should set the IV to deliver 33 drops per minute to infuse the antibiotic correctly. Choices A, B, and C are incorrect as they do not match the calculated drops per minute based on the provided values.

5. The nurse is counting a client's respiratory rate. During a 30-second interval, the nurse counts six respirations, and the client coughs three times. In repeating the count for a second 30-second interval, the nurse counts eight respirations. Which respiratory rate should the nurse document?

• A. 14
• B. 16
• C. 17
• D. 28

Correct answer: B

Rationale: The most accurate respiratory rate is the second count obtained by the nurse, which was not interrupted by coughing. The nurse counted eight respirations over 30 seconds, so doubling this count gives a respiratory rate of 16 breaths per minute. This calculation is based on the assumption that the client's breathing pattern remained relatively stable during the two 30-second intervals. Options A, C, and D are incorrect because they do not reflect the accurate count obtained without interruptions. Choice B (16) is the correct answer as it reflects the uninterrupted count of respirations by the nurse.
