Nursing Elites

1. When planning care for a 10-year-old child with pneumonia receiving oxygen at 5l/min per nasal cannula, what principle of oxygen administration should the nurse consider?

• A. Avoid administration of oxygen at high levels for extended periods.
• B. Increase oxygen flow rate if the child is still tachypneic.
• C. Reduce oxygen levels gradually after symptoms improve.
• D. Humidify the oxygen to prevent drying of mucous membranes.

Correct answer: A

Rationale: The correct principle of oxygen administration to consider is to avoid administering oxygen at high levels for extended periods. High levels of oxygen for prolonged periods can lead to oxygen toxicity, especially in pediatric patients. Increasing the oxygen flow rate based on tachypnea may not be necessary and can potentially lead to oxygen toxicity. Gradually reducing oxygen levels after symptoms improve may compromise the child's oxygenation. While humidifying oxygen is important to prevent drying of mucous membranes, the primary concern in this case is to avoid high oxygen levels for an extended duration to prevent oxygen toxicity.

2. A 26-year-old female client is admitted to the hospital for treatment of a simple goiter, and levothyroxine sodium (Synthroid) is prescribed. Which symptoms indicate to the nurse that the prescribed dosage is too high for this client?

• A. Palpitations and shortness of breath
• B. Bradycardia and constipation
• C. Lethargy and lack of appetite
• D. Muscle cramping and dry, flushed skin

Correct answer: A

Rationale: The correct answer is A. An overdose of thyroid preparation generally manifests symptoms of an agitated state such as tremors, palpitations, shortness of breath, tachycardia, increased appetite, agitation, sweating, and diarrhea. Palpitations and shortness of breath are signs of excessive thyroid medication. Choices B, C, and D are incorrect symptoms for a dosage that is too high. Bradycardia and constipation, lethargy and lack of appetite, muscle cramping and dry, flushed skin are more indicative of hypothyroidism or an insufficient dosage of levothyroxine.

3. A client with a history of chronic kidney disease is scheduled for a CT scan with contrast. Which laboratory value should the nurse review before the procedure?

• A. Serum potassium
• B. Blood urea nitrogen (BUN)
• C. Serum creatinine
• D. Serum glucose

Correct answer: C

Rationale: Before a CT scan with contrast, the nurse should review the serum creatinine level. This is crucial in assessing kidney function because contrast agents can potentially worsen renal function, leading to contrast-induced nephropathy. Monitoring serum creatinine helps in identifying patients at risk and taking necessary precautions. Serum potassium (Choice A) is important in conditions like hyperkalemia but is not the priority before a contrast CT scan. Blood urea nitrogen (BUN) (Choice B) is another renal function test but is not as specific as serum creatinine for assessing kidney function. Serum glucose (Choice D) is important in monitoring blood sugar levels, especially in diabetic patients, but it is not directly related to the risk of contrast-induced nephropathy in this scenario.

4. The nurse is caring for a client with a history of myocardial infarction who is experiencing chest pain. Which intervention should the nurse implement first?

• A. Administer oxygen therapy as prescribed.
• B. Obtain an electrocardiogram (ECG).
• C. Administer nitroglycerin sublingually as prescribed.
• D. Administer aspirin as prescribed.

Correct answer: A

Rationale: Administering oxygen therapy is the priority intervention in managing chest pain in a client with a history of myocardial infarction. Oxygen helps improve oxygenation to the heart muscle, which is crucial in reducing further damage. Obtaining an electrocardiogram (ECG) is important to assess for changes indicative of myocardial infarction, but providing oxygen takes precedence as it directly addresses the physiological need for oxygen. Administering nitroglycerin and aspirin are important interventions but are typically implemented after oxygen therapy to address vasodilation and antiplatelet effects, respectively.

5. A female client reports that she drank a liter of a solution to cleanse her intestines but vomited immediately after. How many ml of fluid intake should the nurse document?

• A. 1000 ml
• B. 800 ml
• C. 760 ml
• D. 500 ml

Correct answer: C

Rationale: The correct answer is 760 ml. One liter equals 1000 ml. As the client vomited immediately after drinking, she would have expelled approximately 240 ml (1 cup). Subtracting this from the initial intake of 1000 ml gives us 760 ml as the remaining fluid intake that should be documented. Choices A, B, and D are incorrect because they do not reflect the correct calculation of subtracting the amount vomited from the initial intake.
