A client receiving epoetin alfa therapy for anemia is being monitored for therapeutic effects. Which of the following laboratory values indicates the medication is effective?

A. White blood cell count

B. Hematocrit

C. Platelet count

D. Red blood cell count

Correct Answer: B
Rationale: The correct answer is B: Hematocrit. An increase in hematocrit levels indicates the effectiveness of epoetin alfa in treating anemia. Hematocrit reflects the percentage of red blood cells in the blood, so an increase in hematocrit signifies an improvement in the patient's red blood cell count and oxygen-carrying capacity. Choices A, C, and D are incorrect because white blood cell count, platelet count, and red blood cell count do not directly reflect the therapeutic effects of epoetin alfa in treating anemia.

A nurse is preparing to administer an intramuscular injection to an adult client. At what angle should the nurse administer the medication using the ventrogluteal site?

• A. a 45-degree angle
• B. a 60-degree angle
• C. a 75-degree angle
• D. a 90-degree angle

Correct Answer: D
Rationale: Intramuscular injections in the ventrogluteal site should be administered at a 90-degree angle. This angle ensures that the medication reaches the muscle tissue effectively. Angles less than 90 degrees can cause subcutaneous injection instead of intramuscular, leading to slower absorption of the medication. Angles greater than 90 degrees risk hitting bone or nerves, causing unnecessary pain or injury. Therefore, the correct angle for administering intramuscular injections in the ventrogluteal site is 90 degrees.

A nurse is preparing to administer ondansetron to a client. Which of the following therapeutic effects should the nurse expect from this medication?

• A. Decreased nausea
• B. Increased appetite
• C. Increased heart rate
• D. Relief of headache

Correct Answer: A
Rationale: The correct answer is A: Decreased nausea. Ondansetron is classified as an antiemetic medication, which means it is used to relieve nausea and vomiting by blocking serotonin in the chemoreceptor trigger zone. Therefore, the nurse administering ondansetron should expect a therapeutic effect of decreased nausea. Choice B, increased appetite, is incorrect as ondansetron does not affect appetite. Choice C, increased heart rate, is incorrect as ondansetron does not have a direct effect on heart rate. Choice D, relief of headache, is also incorrect as the primary therapeutic effect of ondansetron is to alleviate nausea and vomiting, not headaches.

A nurse is reviewing a client's new prescription for albuterol. What client education should the nurse provide?

• A. You may experience a dry cough after taking this medication
• B. Use this medication only as a rescue inhaler
• C. Take this medication with food to avoid nausea
• D. Use this medication daily to prevent asthma attacks

Correct Answer: B
Rationale: The correct answer is B. Albuterol is a rescue inhaler that should be used during asthma attacks to provide quick relief by opening the airways. Using it daily as a preventive measure is not recommended. Choice A is incorrect because a dry cough is not a common side effect of albuterol. Choice C is incorrect as albuterol does not need to be taken with food. Choice D is incorrect because albuterol is not meant to be used daily for asthma prevention.

A nurse is caring for a client who has been prescribed amoxicillin. Which of the following client history findings requires the nurse to clarify the medication prescription?

• A. Hypertension
• B. Peptic ulcer disease
• C. Asthma
• D. Gastroesophageal reflux disease

Correct Answer: C
Rationale: The correct answer is C. Clients with a history of asthma should avoid amoxicillin due to potential hypersensitivity reactions. Amoxicillin can trigger asthma exacerbations in some individuals. Hypertension (choice A), peptic ulcer disease (choice B), and gastroesophageal reflux disease (choice D) are not contraindications for amoxicillin use, so they do not require the nurse to clarify the medication prescription in this case.
