Correct Answer: C

Rationale: The correct answer is C: Auscultate the newborn's apical pulse for 60 seconds. When assessing a newborn, it is essential to auscultate the apical pulse for a full 60 seconds to accurately determine their heart rate. This method allows for a more precise measurement, considering the variability in heart rates in newborns. Choice A is incorrect because tympanic thermometers are not typically used for newborns due to their ear canals being small and not fully developed. Choice B is incorrect as pulling the pinna forward is not necessary for assessing the apical pulse. Choice D is incorrect as measuring head circumference involves a different assessment and is not relevant to determining the heart rate of a newborn.

Correct Answer: B

Rationale: In this scenario, the appropriate action for the nurse to take when a client reports severe postoperative pain of 8 out of 10 is to administer oxycodone 10 mg PO. Oxycodone is a potent analgesic that is more effective in managing severe pain compared to ibuprofen, making choice A incorrect. Repositioning the client to the unaffected side or applying a cold compress may provide some comfort but are not the priority interventions for severe postoperative pain, making choices C and D less appropriate.

Correct Answer: D

Rationale: The correct answer is D, oatmeal. Oatmeal contains insoluble fiber, which can exacerbate the symptoms of irritable bowel syndrome. Choices A, B, and C are not typically problematic for individuals with IBS. Lean cuts of pork, low-fat yogurt, and white bread are generally well-tolerated and may even be recommended as part of a balanced diet for individuals with IBS.

Correct Answer: A

Rationale: The correct answer is A. Ibuprofen is an NSAID that can increase the risk of bleeding during a colonoscopy due to its effects on platelet function. It is important to report this finding to the provider to consider alternative pain management options. Choices B, C, and D are not the most pertinent to report for a colonoscopy. Asthma and a history of diverticulitis are relevant medical history but do not directly impact the colonoscopy procedure. Drinking one glass of wine daily is not a concern specifically related to the colonoscopy procedure.

Correct Answer: C

Rationale: An increased respiratory rate is a sign of fluid volume deficit as the body attempts to compensate for decreased blood volume. Jugular vein distention, bradycardia, and bounding pulses are not typical findings of fluid volume deficit. Jugular vein distention is more commonly associated with fluid volume overload, bradycardia can be a sign of fluid volume excess or other issues, and bounding pulses are not typically seen in fluid volume deficit.
