A nurse is caring for a client who is postoperative following a mitral balloon valvuloplasty.
Which of the following areas should the nurse auscultate to assess the mitral area of the heart?

Choice A rationale

A guardian's statement that a child fell off a swing is a common and plausible explanation for a fractured arm. This type of injury is consistent with the normal activities of a preschooler, and it does not inherently suggest abuse. The nurse should continue with a thorough physical assessment and gather additional history, but this statement alone is not a red flag.

Choice B rationale

Crying loudly when a fractured arm is moved is a normal, expected reaction to pain. The child is experiencing acute pain from the injury, and any movement of the affected limb would cause a significant increase in discomfort. This is not a warning sign of maltreatment but rather a natural physiological response to a painful stimulus.

Choice C rationale

A guardian wanting to accompany a child to the radiology department is a typical and often protective behavior. Many parents wish to provide emotional support to their child during stressful medical procedures. This action demonstrates parental involvement and concern for the child's well-being and is not indicative of abuse or neglect.

Choice D rationale

A delay in seeking medical care for a significant injury, such as a fractured arm, is a major red flag for child maltreatment. This delay suggests that the guardian may be attempting to hide the cause of the injury or is neglectful of the child's health needs. Timely medical attention for a painful injury is the standard of care. .

Choice A rationale

Tetracycline binds to divalent and trivalent cations such as calcium, magnesium, and aluminum. Milk and dairy products are rich in calcium, so taking tetracycline with milk significantly reduces its absorption from the gastrointestinal tract, rendering the medication less effective. The drug should be taken on an empty stomach with a full glass of water.

Choice B rationale

Taking tetracycline at bedtime is not a recommended practice for this drug. Although some medications are taken at night to avoid side effects or promote sleep, tetracycline can cause gastroesophageal reflux or esophagitis, particularly when a person lies down soon after ingestion. It is important to remain upright for at least 30 minutes after taking the medication.

Choice C rationale

Photosensitivity is a well-documented adverse effect of tetracycline. The drug sensitizes the skin to ultraviolet light, leading to an exaggerated sunburn reaction. This is due to the drug's accumulation in the skin and its ability to absorb light energy. Clients must be advised to use sunscreen, wear protective clothing, and avoid prolonged sun exposure.

Choice D rationale

Tetracycline is known to cause gastrointestinal side effects, but diarrhea is far more common than constipation. This is often due to the disruption of the normal gut flora, which can lead to opportunistic infections like Clostridium difficile. While not exclusively causing diarrhea, constipation is not a typical adverse effect and should not be the primary teaching point. *.
