Correct Answer: D

Rationale: Choice D is the correct answer because having the 4-year-old help feed the four-month-old a bottle in the kitchen while the mother makes supper shows supervision of the infant by the older child in a safe environment. This choice indicates that the mother understands safety precautions by involving the older child in a caregiving task under her supervision. Choices A, B, and C are incorrect because they involve unsafe practices such as placing the infant on the floor unsupervised, positioning the infant car seat in the front seat, and not providing direct supervision of the children during naptimes.

Correct Answer: A

Rationale: The correct action to ensure that otic medication reaches the inner ear is to press gently on the tragus. The tragus is a small cartilaginous projection in front of the ear canal. Pressing on it helps to straighten the ear canal, allowing the medication to reach the inner ear. Packing cotton or moving the auricle can obstruct the ear canal and prevent proper medication delivery. Tilting the client's head backward is not necessary and may not facilitate the medication reaching the inner ear as effectively as pressing on the tragus.

Correct Answer: C

Rationale: When a client reports abdominal cramping during a cleansing enema, it is important for the nurse to reassure the client that cramping is a common side effect. This reassurance helps the client understand that the cramping is normal and may subside once the enema is completed. Instructing the client to hold their breath and bear down (Choice A) is not appropriate and may cause discomfort. Clamping the enema tubing (Choice B) is unnecessary and could lead to complications. Raising the level of the enema fluid container (Choice D) does not address the client's discomfort due to cramping. Therefore, the most suitable action is to provide reassurance to the client about the common occurrence of cramping during the enema.

Correct Answer: C

Rationale: The correct sequence for oral care is to clean the outer tooth surfaces first, followed by cleaning the inner tooth surfaces, then the roof of the mouth, gums, and inside cheeks with a toothette. Brushing the tongue should be the final step in the oral care procedure. Therefore, option C is the correct choice. Options A, B, and D are incorrect because they do not follow the correct order for providing oral care to a patient.

Correct Answer: B

Rationale: Adding a spacer device to the MDI canister is the best recommendation in this scenario. The spacer device helps to improve coordination and medication delivery by allowing the client more time to inhale the medication effectively. Nebulized treatments for home care (Choice A) involve a different delivery method and are not directly related to improving coordination with MDIs. Asking a family member to assist (Choice C) may not address the core issue of coordination between releasing the medication and inhalation. Requesting a visiting nurse (Choice D) may not be necessary if the client can improve coordination with the spacer device.
