Correct Answer: B

Rationale: The correct answer is that chemotherapy is a systemic treatment affecting both tumor and normal cells. 5-FU, as an antimetabolic drug, inhibits DNA synthesis and interferes with cell replication systemically. It affects all rapidly growing cells, including malignant and normal ones. This drug is used as adjuvant therapy for various cancers. Choice A is incorrect because chemotherapy affects both tumor and normal cells, not just tumor cells. Choice C is incorrect as chemotherapy has been proven effective in treating cancer. Choice D is incorrect because chemotherapy often causes side effects like bone marrow depression, anorexia, stomatitis, nausea, and vomiting.

Correct Answer: B

Rationale: Alcoholism places a client at risk for developing cirrhosis due to the liver damage caused by excessive alcohol consumption. Type I diabetes, leukemia, and glaucoma are not directly associated with cirrhosis. While diabetes can lead to other health complications, it does not directly cause cirrhosis. Leukemia is a type of blood cancer that does not affect the liver in a way that leads to cirrhosis. Glaucoma is an eye condition that has no direct link to cirrhosis.

Correct Answer: D

Rationale: Vaccines are one of the most effective methods of preventing and controlling certain communicable diseases. The smallpox vaccine is not currently in use because the smallpox virus has been declared eradicated from the world's population. Diseases such as polio, diphtheria, pertussis, and measles are mostly controlled by routine childhood immunization. They have not, however, been eradicated, so children need to be immunized against these diseases. Choices A, B, and C contain vaccines that do not protect against preventable diseases like polio, pertussis, and measles. Therefore, the correct choice is D.

Correct Answer: B

Rationale: The correct answer is to palpate for a thrill. A thrill should be present in a functioning arteriovenous fistula (AVF) and indicates good blood flow. The client should be educated to check for this sensation daily at home to monitor the AVF's patency. Visible pulsations are not typically observed in an AVF. Percussion for dullness does not provide relevant information about the AVF. Auscultation of blood pressure is not a standard practice in assessing an AVF. However, auscultation of the AVF for a bruit, a sound indicating turbulent blood flow, is crucial in evaluating the AVF's patency.

Correct Answer: C

Rationale: Acute Pain is the most appropriate nursing diagnosis for a client experiencing acute pancreatitis because it is a common symptom associated with this condition. Pancreatitis often presents with severe abdominal pain that may radiate to the back. Confusion, Latex Allergy, and Constipation are not typically associated with acute pancreatitis. Confusion may occur in severe cases of pancreatitis with complications, but acute pain is the priority nursing diagnosis due to its prevalence and impact on the client's well-being.
