Nursing Elites

1. The nurse analyzes the results of a patient's arterial blood gases (ABGs). Which finding would require immediate action?

• A. The bicarbonate level (HCO3) is 31 mEq/L
• B. The arterial oxygen saturation (SaO2) is 92%
• C. The partial pressure of CO2 in arterial blood (PaCO2) is 31 mm Hg
• D. The partial pressure of oxygen in arterial blood (PaO2) is 59 mm Hg

Correct answer: D

Rationale: While all the values are abnormal, the low PaO2 level of 59 mm Hg indicates that the patient is at a critical point on the oxyhemoglobin dissociation curve. At this level, a small decrease in PaO2 can lead to a significant drop in oxygen saturation and compromise tissue oxygenation. Therefore, immediate intervention is necessary to improve the patient's oxygenation status. Choice A (HCO3 of 31 mEq/L) may indicate metabolic alkalosis or compensation for respiratory acidosis; however, it does not require immediate action in this scenario. Choice B (SaO2 of 92%) is slightly low but not critically low to require immediate action. Choice C (PaCO2 of 31 mm Hg) is within the normal range and does not indicate immediate danger to the patient.

2. The nurse develops a plan of care to prevent aspiration in a high-risk patient. Which nursing action will be most effective?

• A. Turn and reposition immobile patients at least every 2 hours.
• B. Place patients with altered consciousness in side-lying positions.
• C. Monitor for respiratory symptoms in immunosuppressed patients.
• D. Insert nasogastric tube for feedings in patients with swallowing problems.

Correct answer: B

Rationale: To prevent aspiration in a high-risk patient, the most effective nursing action is to place patients with altered consciousness in side-lying positions. This position helps decrease the risk of aspiration as it prevents pooling of secretions and facilitates drainage. Turning and repositioning immobile patients every 2 hours is essential for preventing pressure ulcers and improving circulation but does not directly address the risk of aspiration. Monitoring respiratory symptoms in immunosuppressed patients is crucial to detect pneumonia early, but it does not directly prevent aspiration. Inserting a nasogastric tube for feedings in patients with swallowing problems may be necessary for nutritional support but does not address the risk of aspiration directly. Patients at high risk for aspiration include those with altered consciousness, difficulty swallowing, and those with nasogastric intubation, among others. Placing patients with altered consciousness in a side-lying position is a key intervention to reduce the risk of aspiration in this population. Other high-risk groups for aspiration include those who are seriously ill, have poor dentition, or are on acid-reducing medications.

3. Why should a 30-year-old Caucasian woman who works the night shift take Vitamin D supplements?

• A. It's a standard part of the overall nutritional treatment for the prevention of osteomalacia.
• B. It helps your intestines absorb calcium, which is important for bone formation.
• C. It stimulates skin cells to produce calcium, which is then released into the bloodstream to be used for bone formation.
• D. Vitamin D supplements should not be taken by someone of your age.

Correct answer: B

Rationale: The correct answer is B: 'It helps your intestines absorb calcium, which is important for bone formation.' Vitamin D plays a crucial role in aiding the absorption of calcium from the intestines into the bloodstream, which is essential for bone health and formation. Choice A is incorrect because it does not specifically address the role of Vitamin D in calcium absorption. Choice C is incorrect as Vitamin D does not stimulate skin cells to produce calcium; rather, it helps regulate calcium levels in the body. Choice D is incorrect as age alone is not a contraindication for Vitamin D supplementation; the need for supplementation is based on individual health status and risk factors.

4. The nurse is caring for a 73-year-old man with cirrhosis. Which data obtained by the nurse during the assessment will be of most concern?

• A. The patient complains of right upper-quadrant pain upon palpation.
• B. The patient's hands flap back and forth when the arms are extended.
• C. The patient has ascites and a 2-kg weight gain from the previous day.
• D. The patient's skin has multiple spider-shaped blood vessels on the abdomen.

Correct answer: B

Rationale: The most concerning data obtained by the nurse is the patient's hands flapping back and forth when the arms are extended, indicating asterixis, which is associated with hepatic encephalopathy. This condition can progress to hepatic coma and requires immediate attention. The presence of spider angiomas and right upper-quadrant abdominal pain are common findings in cirrhosis and do not warrant urgent intervention. Although ascites and weight gain suggest the need for treatment, they are not as alarming as the neurologic manifestations seen in hepatic encephalopathy.

5. A 45-year-old woman is prescribed ropinirole (Requip) for Parkinson's Disease. The patient is living at home with her daughter. The nurse is most concerned about which side effect of ropinirole?

• A. Slurred speech
• B. Sudden dizziness
• C. Mask-like facial expression
• D. Stooped posture

Correct answer: B

Rationale: The correct answer is 'Sudden dizziness.' Dizziness and orthostatic hypotension are serious adverse effects of ropinirole that can lead to an increased risk of falls. Ropinirole belongs to the drug class of dopamine agonists, which mimic dopamine in the brain (Parkinson's Disease is characterized by a lack of dopamine). 'Slurred speech' is not a common side effect of ropinirole. 'Mask-like facial expression' and 'Stooped posture' are more associated with the progression of Parkinson's Disease itself rather than a side effect of ropinirole.
