1. What can cause a low pulse oximetry reading?

• A. Hyperthermia
• B. Increased hemoglobin level
• C. Inadequate peripheral circulation
• D. Low altitudes

Correct answer: C

Rationale: Inadequate peripheral circulation can cause a low pulse oximetry reading by limiting blood flow to the area being measured, leading to inaccurate oxygen saturation readings. Hyperthermia (choice A) is an elevated body temperature and does not directly affect pulse oximetry readings. An increased hemoglobin level (choice B) would actually lead to higher oxygen-carrying capacity in the blood, resulting in normal or increased pulse oximetry readings. Low altitudes (choice D) typically do not cause low pulse oximetry readings unless there are other underlying conditions affecting oxygen levels.

2. A nurse is reviewing laboratory results for a client receiving chemotherapy. Which result should the nurse report to the provider?

• A. WBC 3,000/mm³
• B. Hemoglobin 12 g/dL
• C. Platelet count 250,000/mm³
• D. Serum sodium 140 mEq/L

Correct answer: A

Rationale: The correct answer is A: WBC 3,000/mm³. A WBC count of 3,000/mm³ indicates neutropenia, which is a condition characterized by a low level of white blood cells, specifically neutrophils. Neutropenia increases the risk of infection and requires immediate medical attention, especially in clients undergoing chemotherapy. Reporting this result to the provider promptly is crucial for further evaluation and intervention. Choices B, C, and D are within normal ranges and do not pose an immediate risk to the client's health. Hemoglobin of 12 g/dL, platelet count of 250,000/mm³, and serum sodium of 140 mEq/L are all normal values and would not typically require immediate reporting unless there are specific concerns related to the individual client's condition.

3. A client has been prescribed metformin. What should be included in the teaching?

• A. It can cause weight gain
• B. Take it with food
• C. It is an insulin
• D. Monitor for hyperglycemia

Correct answer: B

Rationale: The correct answer is to take metformin with food. This is important to minimize gastrointestinal side effects and improve absorption. Choice A is incorrect as metformin is not typically associated with weight gain. Choice C is wrong as metformin is not an insulin but a medication that helps control blood sugar levels. Choice D is also incorrect as metformin is not known to cause hyperglycemia.

4. A nurse is caring for a client who has been prescribed furosemide. Which of the following foods should the nurse encourage the client to include in their diet?

• A. Table salt
• B. Egg yolks
• C. White wine
• D. Oranges

Correct answer: D

Rationale: Furosemide is a potassium-wasting diuretic, so clients should consume potassium-rich foods like oranges to prevent hypokalemia. Oranges are a good source of potassium. Table salt, egg yolks, and white wine do not provide significant amounts of potassium and are not beneficial for a client taking furosemide.

5. A client is prescribed insulin glargine. Which of the following should the nurse instruct the client to do regarding administration of this medication?

• A. Inject insulin glargine 30 minutes before a meal.
• B. Shake the insulin vial before administration.
• C. Administer insulin glargine once daily at bedtime.
• D. Take insulin glargine with short-acting insulin.

Correct answer: C

Rationale: The correct answer is C: Administer insulin glargine once daily at bedtime. Insulin glargine is a long-acting insulin that provides a basal level of insulin throughout the day. It should be given at the same time each day, usually at bedtime, to maintain a consistent blood sugar level. Choices A, B, and D are incorrect. Injecting insulin glargine before a meal (Choice A) is not necessary as it is a long-acting insulin. Shaking the insulin vial (Choice B) is not recommended as it may cause bubbles to form, affecting the accuracy of the dose. Taking insulin glargine with short-acting insulin (Choice D) is not a typical practice as insulin glargine is used for basal insulin coverage.
