Correct Answer: B

Rationale: The correct instruction for the client using a corticosteroid inhaler to prevent a common side effect is to rinse the mouth with water after using the inhaler. Corticosteroid inhalers can lead to oral thrush, a fungal infection in the mouth. Rinsing the mouth helps reduce the risk of developing oral thrush. Choices A, C, and D are incorrect because using the inhaler only when experiencing symptoms, increasing fluid intake, or avoiding eating/drinking for 30 minutes after use are not directly related to preventing oral thrush, which is the common side effect associated with corticosteroid inhalers.

Correct Answer: B

Rationale: The correct answer is B: Hemoglobin. Epoetin alfa (Epogen) is a medication commonly used in clients with chronic kidney disease to stimulate red blood cell production. Monitoring hemoglobin levels is crucial to assess the effectiveness of epoetin alfa therapy. Hemoglobin levels reflect the oxygen-carrying capacity of the blood and indicate if the medication is successfully treating anemia associated with chronic kidney disease. Option A, serum creatinine, is a marker of kidney function, not the primary indicator of epoetin alfa effectiveness. Option C, blood urea nitrogen (BUN), is a measure of kidney function and hydration status. Option D, platelet count, assesses clotting ability and is unrelated to monitoring the effectiveness of epoetin alfa in treating anemia in chronic kidney disease.

Correct Answer: C

Rationale: The correct answer is C: Friction. The amount of friction is crucial in effective hand hygiene to remove microorganisms. Rubbing hands together with friction helps to dislodge and remove dirt, oils, and microorganisms. While temperature and soap are important factors in hand hygiene, the mechanical action of friction plays a more significant role in physically removing contaminants. Time is also important in hand hygiene practice, but without adequate friction, the effectiveness of the process is compromised.

Correct Answer: B

Rationale: The correct answer is B. Rheumatic fever often follows a strep throat infection, which is why the nurse should suspect this association. Strep throat is caused by Group A Streptococcus bacteria, which can trigger an abnormal immune response leading to rheumatic fever. Choices A, C, and D are incorrect because chickenpox, ear infections, and fungal skin infections are not typically associated with rheumatic fever.

Correct Answer: B

Rationale: The correct answer is B: 'During the inhalation.' Administering the medication while inhaling ensures proper delivery to the lungs. Inhaling the medication allows it to reach the lungs effectively for optimal therapeutic benefit. Choices A, C, and D are incorrect because administering the medication after exhalation or at the end of inhalations may result in improper drug delivery and reduced therapeutic effects.
