A 3-year-old child has had multiple tooth extractions while under general anesthesia. The client returns from the post-anesthesia care unit crying but awake. Which approach is likely to be successful?

Correct Answer: C

Rationale: In this scenario, it is crucial to prioritize the comfort of the child. By examining the mouth last, discomfort is minimized, and the child is given the opportunity to settle down. Choosing to examine the mouth first may escalate the distress of the child further. While reassuring the child is important, in this case, addressing the physical discomfort before providing emotional reassurance is more effective. Offering a pacifier may provide some comfort, but addressing the immediate physical discomfort by examining the mouth last is the most appropriate action to help the child settle down after the procedure.

Correct Answer: A

Rationale: To calculate the mL to administer, use the formula: Dose required (mg) · Stock concentration (mg/mL) = Volume to administer (mL). In this case, 10 mg · 40 mg/mL = 0.25 mL. However, when rounding to the nearest tenth, the answer should be 0.3 mL. Therefore, the nurse should administer 0.3 mL. Choice A is the correct answer. Choice B (0.25 mL) is the result obtained before rounding. Choice C (0.4 mL) and Choice D (0.5 mL) are incorrect calculations.

Correct Answer: D

Rationale: In acute pancreatitis, hypocalcemia (low serum calcium) is a critical finding that is associated with a poor prognosis and requires immediate attention. Serum amylase and lipase are typically elevated in acute pancreatitis due to pancreatic inflammation, but they are not indicators of severity. Blood glucose levels may be elevated due to stress or underlying conditions but are not directly related to the severity of acute pancreatitis. Therefore, the most concerning value in this scenario is the low serum calcium level, which can have significant implications for the client's prognosis.

Correct Answer: B

Rationale: The toddler with severe deep abrasions covering 98% of the body would be prioritized for treatment last because these extensive injuries may require immediate attention and resources. The other choices present serious conditions but are not as severe or life-threatening as the toddler's injuries. The infant with an intermittent bulging anterior fontanel may have signs of increased intracranial pressure, requiring prompt evaluation. The preschooler's fractures, though serious, can be managed without immediate critical intervention. The school-age child with singed eyebrows and hair may have suffered burns but does not exhibit injuries as severe as the toddler's deep abrasions.

Correct Answer: A

Rationale: Refrigeration can kill the ova and parasites present in the stool specimen, leading to inaccurate test results. Storing the specimen in a cold environment can disrupt the integrity of the parasites and ova, affecting the accuracy of the test. Collecting the specimen in a sterile container (Choice B) is the correct procedure to prevent external contamination. Delaying the collection of the specimen (Choice C) may affect the freshness of the sample but does not directly impact the test results. Using a non-contaminated collection container (Choice D) is essential to maintain the sample's integrity but does not relate to the risk of killing ova and parasites through refrigeration.

Correct Answer: A

Rationale: The correct answer is A: Educating clients about the recommended immunization schedule for adults. This activity falls under primary prevention, which aims to prevent the onset of illness or injury. Immunizations are a proactive measure to protect individuals from developing certain diseases. Choices B, C, and D involve managing chronic illnesses, providing counseling for mental health issues, and offering support for individuals who have already experienced cancer, respectively. These activities are more aligned with secondary or tertiary prevention, focusing on managing existing conditions or preventing complications in those already affected.

Correct Answer: B

Rationale: During a Weber test, the nurse should place an activated tuning fork in the middle of the client's forehead. This test is used to assess for lateralization of sound in a client with possible hearing issues. Choice A is incorrect because the Weber test does not involve delivering high-pitched sounds at random intervals. Choice C is incorrect as it describes the Rinne test, not the Weber test. Choice D is incorrect as whispering words into one ear is not part of the Weber test procedure.

Correct Answer: A

Rationale: Elevating the head of the client's bed is the most appropriate action in this situation. It helps reduce noisy respirations and improves comfort for clients with terminal illnesses by facilitating better air exchange. Administering an opioid medication may not address the immediate issue of noisy respirations and shortness of breath caused by secretions in the airway. Performing oral suctioning without proper assessment and indication can be uncomfortable for the client and may not be necessary. Placing the client in a prone position can further compromise breathing and is not recommended for a client with respiratory distress.

Correct Answer: A

Rationale: The pulse deficit is calculated by finding the difference between the apical and radial pulse rates. In this case, the difference is 84 - 68 = 16. This indicates that there is a pulse deficit of 16 beats per minute. Choices B, C, and D are incorrect as they do not accurately reflect the difference between the two pulse rates.
