Correct Answer: D

Rationale: A pulse of 54/min indicates bradycardia, which is a side effect of propranolol, a beta-blocker. The medication should be withheld if the client's pulse drops below 60/min. The other findings (sodium levels, blood pressure, and potassium levels) are not directly indicative of the need to withhold propranolol.

Correct Answer: D

Rationale: The correct statement to include in the teaching about amniocentesis is that the client should report if they experience any contractions after the procedure. This is crucial because contractions could indicate preterm labor or other complications following the amniocentesis. Choices A and B are incorrect as a full bladder is not required for the procedure, and magnesium sulfate is not typically given before an amniocentesis. Choice C is incorrect as the procedure usually takes about 20-30 minutes to complete.

Correct Answer: C

Rationale: In acute pancreatitis, the nurse should expect elevated blood glucose levels. This is due to impaired insulin production by the inflamed pancreas. While serum amylase and lipase levels are typically elevated in acute pancreatitis, blood glucose levels are also affected due to the pancreatic dysfunction. Therefore, choices A and B are incorrect. Elevated calcium levels are not typically associated with acute pancreatitis, making choice D incorrect.

Correct Answer: B

Rationale: The correct action for the nurse to take first when a client with a nasogastric tube reports feeling nauseated is to check the client's bowel sounds. This assessment helps the nurse evaluate for possible complications, such as a blockage or decreased gastric motility, that could be causing the nausea. Administering an antiemetic (Choice A) should not be the first action without assessing the underlying cause of the nausea. Slowing the rate of the feeding (Choice C) may be appropriate but is not the priority until further assessment is done. Placing the client in a supine position (Choice D) is not typically indicated for managing nausea in this situation.

Correct Answer: D

Rationale: The correct answer is D: Red, open sores in the mouth. Stomatitis, a common side effect of chemotherapy, presents with red, open sores in the mouth, which can be painful and increase the risk of infection. Choices A, B, and C are incorrect because stomatitis typically does not manifest as dry, cracked lips, bleeding gums, or foul-smelling breath.
