HESI Fundamentals Exam

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: When a client is using a nasal cannula for oxygen therapy, the areas prone to skin damage are the tops of the ears and around the nostrils. The pressure exerted by the cannula on these areas can lead to skin breakdown, so it is important for the nurse to observe these sites for any signs of damage. The correct answer is 'Tops of the ears.' Choices 'Bridge of the nose' and 'Over the cheeks' are not typically areas where skin damage related to the cannula would occur, making them incorrect choices.

Correct Answer: C

Rationale: The correct answer is C: Back. Back injuries are common among healthcare workers, especially nurses, due to improper lifting techniques and bending. Working on an orthopedic rehabilitation unit involves frequent lifting and positioning of patients, putting the nurse at risk of back injuries. Preventing back injuries is crucial for maintaining the nurse's health and ability to provide care effectively. Choices A, B, and D are incorrect because while lifting and positioning patients may involve these body parts, back injuries are most likely to occur due to the strain and stress placed on the back during such activities.

Correct Answer: C

Rationale: To calculate the drops per minute for the IV infusion, first determine the total drops to be infused over 8 hours. 1,000 ml to be infused over 8 hours means 125 ml per hour (1000 ml / 8 hours = 125 ml/hr). Since the infusion set delivers 10 drops per ml, 125 ml/hr x 10 drops/ml = 1250 drops/hr. To find drops per minute, divide the drops per hour by 60 (minutes in an hour): 1250 drops/hr / 60 minutes = 20.83 drops/minute, which rounds up to 21 drops per minute (Option C). This rate ensures the correct infusion rate over 8 hours. Choices A, B, and D are incorrect calculations and do not provide the appropriate infusion rate needed to administer the IV over the specified time period.

Correct Answer: A

Rationale: The correct answer is option A: Inability of the toddler to cry or speak. In cases of choking, the inability to cry or speak indicates a severe airway obstruction where the Heimlich maneuver is necessary to clear the obstruction and establish a patent airway. Option B, coughing forcefully, represents a partial obstruction where the child can still move air, making the Heimlich maneuver not immediately necessary. Option C, gagging but able to breathe, suggests a partial obstruction where air is moving, and the child can still breathe, not requiring immediate intervention like the Heimlich maneuver. Option D, wheezing during respiration, is more indicative of a lower airway issue such as asthma rather than an upper airway obstruction that necessitates the Heimlich maneuver.
