Pharmacology and the Nursing Process 9th Edition Test Bank

Correct Answer: A

Rationale: The correct answer is A: A rapid, thready pulse. After paracentesis, rapid removal of ascitic fluid can lead to a decrease in intravascular volume, causing hypovolemia and subsequent compensatory mechanisms like tachycardia (rapid pulse). This is a crucial sign that the nurse should monitor for early detection of hypovolemia. B: Decreased peristalsis is not directly related to paracentesis and is not an immediate concern post-procedure. C: Respiratory congestion is not a common complication of paracentesis and is not the most immediate concern. D: An increased temperature is not a typical response to paracentesis and is not a priority observation post-procedure.

Correct Answer: D

Rationale: The correct answer is D: Whisper voice test. This test is used as an initial screening for hearing loss because it is simple, quick, and easily administered by a nurse. The nurse would whisper words or numbers at a specific distance from the patient to assess their ability to hear and repeat the whispered sounds accurately. This test provides a quick indication of potential hearing impairment. The other choices are incorrect: A: Romberg test assesses balance and not hearing. B: Caloric test evaluates the vestibular system, not hearing. C: Otoscopic examination is used to examine the ear canal and tympanic membrane, not to screen for hearing loss.

Correct Answer: D

Rationale: The correct answer is D because assessing for localized ischemia involves evaluating multiple factors. A: Assessing color and temperature helps determine perfusion. B: Checking capillary refill assesses circulation. C: Evaluating pulse rate indicates cardiac output. Doing all of the above provides a comprehensive assessment of arterial flow and potential ischemia. Other choices are incorrect as they do not cover all aspects necessary for a thorough assessment.

Correct Answer: D

Rationale: The correct answer is D because antimetabolites interfere with the synthesis of nucleic acids (RNA and/or DNA), affecting multiple stages of RNA and DNA synthesis. This disruption hinders cell division and leads to cell death. Choices A and B are incorrect because antimetabolites do not specifically target cell division during the M phase or normal cellular processes during the S phase. Choice C is also incorrect because antimetabolites primarily target nucleic acid synthesis rather than altering the chemical structure of DNA or the binding between DNA molecules.

Correct Answer: C

Rationale: The sudden sharp pain in the midepigastric region with a rigid boardlike abdomen in a patient with a bleeding gastric ulcer indicates a perforation of the ulcer. Perforation leads to leakage of gastric contents into the peritoneal cavity, causing peritonitis. This presentation requires immediate surgical intervention. Option A is incorrect as intestinal development does not correlate with the symptoms described. Option B is incorrect because inflammation of the esophagus would not lead to a rigid boardlike abdomen. Option D is incorrect as the sudden onset of symptoms is more indicative of a complication like perforation rather than the development of additional ulcers.
