A nurse is caring for a child who has otitis media with eﬀusion. The nurse should identify which of the following manifestations indicates a tympanic membrane rupture.

Popping sensation when swallowing

Green-blue discharge in the ear canal

Sudden pain relief

Increased temperature

Answer and Explanation

The Correct Answer is C

Choice A: A popping sensation when swallowing is not a sign of a tympanic membrane rupture, as it is a normal phenomenon that occurs when the eustachian tube opens and closes to equalize the pressure between the middle ear and the atmosphere. A popping sensation when swallowing may be associated with otitis media with eﬀusion, which is a condition that causes ﬂuid accumulation behind the eardrum, but it does not indicate a rupture.

Choice B: Green-blue discharge could be indicative of infection but is not as directly related to the rupture event as the sudden pain relief is.

Choice C: The correct answer is sudden relief of pain. This is because the rupture of the tympanic membrane releases the pressure and fluid that has built up in the middle ear, leading to an immediate decrease in pain.

Choice D: An increased temperature is not a sign of a tympanic membrane rupture, as it is a nonspecific symptom that may indicate various conditions, such as inﬂammation, infection, or fever. An increased temperature may be associated with otitis media with eﬀusion, which is a condition that causes ﬂuid accumulation behind the eardrum, but it does not indicate a rupture.

Correct Answer is A

Explanation

Choice A: This statement indicates an understanding of the teaching, as washing all recently used clothing, bedding, and towels in hot water can help eliminate lice and nits (eggs). Lice and nits can survive on fabrics for up to two days and can spread from one person to another through direct or indirect contact. Washing items in hot water can kill lice and nits by exposing them to high temperatures.

Choice B: This statement indicates a lack of understanding of the teaching, as nits will not always be present after treatment. Nits are tiny white or yellow oval-shaped eggs that are attached to the hair shaft near the scalp. Nits can hatch into nymphs (young lice) within seven to ten days and mature into adult lice within nine to twelve days. Nits can be removed by using a fine-toothed comb or by applying products that loosen their grip on the hair.

Choice C: This statement indicates a lack of understanding of the teaching, as treating all family members may not be necessary or eﬀective. Treating all family members can expose them to unnecessary chemicals or medications that may have side effects or cause resistance. Treating all family members may also not prevent reinfestation if there are other sources of exposure such as school or daycare. Only family members who have evidence of lice or nits should be treated.

Choice D: This statement indicates a lack of understanding of the teaching, as throwing out toys that can't be dry cleaned or washed may not be required or practical. Throwing out toys can cause emotional distress or financial burden for the child or the parents. Throwing out toys may also not prevent reinfestation if there are other sources of exposure such as clothing or bedding. Toys that can't be dry cleaned or washed can be sealed in plastic bags for two weeks to suﬀocate the lice and nits.

A. "The insulin can be injected anywhere there is adipose tissue." B. "I will be sure my child rotates sites after 5 injections in one area." C. "I will be sure my child aspirates before injecting the insulin." D. "The insulin should be injected at a 90-degree angle."

Correct Answer is C

Explanation

Choice A: This statement does not indicate a need for further teaching, as it is correct that insulin can be injected anywhere there is adipose tissue. Adipose tissue is the layer of fat under the skin that can absorb insulin and prevent damage to muscles or organs. The common sites for insulin injection are the abdomen, thighs, buttocks, or upper arms.

Choice B: This statement does not indicate a need for further teaching, as it is correct that the child should rotate sites after 5 injections in one area. Rotating sites can prevent lipodystrophy, which is a condition that causes abnormal changes in fat tissue due to repeated injections. Lipodystrophy can affect the appearance and absorption of insulin in the aﬀected area.

Choice C: This statement indicates a need for further teaching, as it is incorrect that the child should aspirate before injecting the insulin. Aspiration is the process of pulling back on the plunger of the syringe to check for blood before injecting the medication. Aspiration is not recommended for insulin injection, as it can cause pain, bruising, or leakage of insulin from the injection site.

Choice D: This statement does not indicate a need for further teaching, as it is correct that insulin should be injected at a 90-degree angle. Injecting insulin at a 90-degree angle can ensure that the medication reaches the adipose tissue and prevents skin irritation or muscle damage. The only exception is if the child has very thin skin or uses very short needles, in which case they may inject at a 45-degree angle.
