Nursing Elites

1. A client without a history of respiratory disease has a pulse oximeter in place after surgery. The nurse monitors the pulse oximeter readings to ensure that oxygen saturation remains above:

• A. 85%
• B. 89%
• C. 95%
• D. 100%

Correct answer: C

Rationale: Pulse oximetry is a noninvasive method of continuously monitoring the oxygen saturation of hemoglobin (SaO2). In the absence of underlying respiratory disease, the expected oxygen saturation level is at least 95%. Oxygen saturation levels below 95% may indicate hypoxemia, which can compromise tissue perfusion and oxygen delivery to vital organs. Therefore, maintaining oxygen saturation above 95% is crucial to ensure adequate oxygenation post-surgery. Choices A, B, and D are incorrect as they represent oxygen saturation levels that are below the expected value for a client without a history of respiratory disease, which should be at least 95%.

2. A client tells the nurse that he has been experiencing frequent heartburn and has been 'living on antacids.' For which acid-base disturbance does the nurse recognize a risk?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: B

Rationale: The correct answer is B: Metabolic alkalosis. In this scenario, the client's frequent use of antacids containing alkaline components can lead to an excess of bicarbonate in the body, causing metabolic alkalosis. Oral antacids work by neutralizing stomach acid, potentially leading to an alkaline shift in the body's pH balance. Choices A, C, and D are incorrect. Metabolic acidosis is not typically associated with antacid use. Respiratory acidosis and respiratory alkalosis are related to respiratory system dysfunction rather than antacid ingestion.

3. Upon admission, a 77-year-old female client presents with confusion, loss of appetite, nausea, vomiting, and headache, with a pulse rate of 43 beats per minute. Which question should the nurse prioritize asking the client or her family?

• A. Does the client have her own teeth or dentures?
• B. Does the client take aspirin, and if so, what is the dosage?
• C. Does the client take nitroglycerin?
• D. Does the client take digitalis?

Correct answer: D

Rationale: The correct answer is D. The client's symptoms suggest digitalis toxicity, a potentially life-threatening condition that requires immediate attention. Digitalis toxicity can present with symptoms such as anorexia, nausea, vomiting, headache, and bradycardia (low pulse rate). Given the client's presentation, it is crucial to assess for digitalis use as elderly individuals are more susceptible to this type of intoxication. Choices A, B, and C are important aspects to consider during the assessment, but in this scenario, the priority lies in identifying and addressing the potential digitalis toxicity due to the severity of symptoms and the need for prompt intervention.

4. A client who underwent preadmission testing 1 week before surgery had blood drawn for several serum laboratory studies. Which abnormal laboratory results should the nurse report to the surgeon’s office? Select all that apply.

• A. Hematocrit 30%
• B. Sodium 141 mEq/L
• C. Hemoglobin 8.9 g/dL
• D. Platelets 210,000 cells/mm3

Correct answer: C

Rationale: The correct answer is C. Hemoglobin level of 8.9 g/dL is below the normal range, indicating anemia. Anemia can affect the body's ability to carry oxygen, impacting surgical outcomes. Hematocrit level is an indirect measure of red blood cells, which also reveals anemia when low. Sodium level of 141 mEq/L and platelet count of 210,000 cells/mm3 are within normal ranges and do not require immediate reporting. Abnormal sodium levels can lead to various issues, but in this scenario, it is not a concern for surgical readiness. Platelet count is vital for blood clotting, and a count of 210,000 cells/mm3 is considered normal, so it does not need urgent attention.

5. When performing a health history on a patient who is to begin receiving a thiazide diuretic to treat heart failure, the nurse will be concerned about a history of which condition?

• A. Asthma
• B. Glaucoma
• C. Gout
• D. Hypertension

Correct answer: C

Rationale: Thiazide diuretics block uric acid secretion, leading to elevated levels that can contribute to gout. Therefore, patients with a history of gout should take thiazide diuretics with caution. Asthma (Choice A), Glaucoma (Choice B), and Hypertension (Choice D) are not directly contraindicated with thiazide diuretics, making choices A, B, and D incorrect.
