A nurse is reporting a client's laboratory tests to the provider to obtain a prescription for the client's daily warfarin.
Which of the following laboratory tests should the nurse plan to report to obtain the prescription for the warfarin?

A) "My child has some swelling around her eyelids and mouth."

In this scenario, the parent reporting swelling around the toddler's eyelids and mouth after receiving immunizations is the nurse's priority concern. Swelling around the eyes and mouth can be indicative of a possible allergic reaction, such as angioedema or anaphylaxis, which can be a serious and life-threatening condition. Immediate assessment and intervention are needed to address this potential allergic reaction.

The other findings, while important, are not as immediately concerning:

B) A temperature of 100.7 degrees Fahrenheit is a mild fever, which can be expected as a side effect of some vaccines. It may not be the nurse's immediate priority, but it should still be monitored.

C) A toddler's decreased feeding of 2 ounces during her last feeding may be related to her discomfort or fever after immunizations. It's essential to monitor this but not an immediate priority.

D) Crying when touched at the injection site is a common response to immunizations and, while uncomfortable for the child, is not typically a cause for immediate concern. However, it should still be addressed with comfort measures.

Choice A rationale:

Crackles in the lungs are a common manifestation of heart failure. Heart failure can cause fluid accumulation in the lungs, leading to crackles upon auscultation. This finding is due to pulmonary congestion and is indicative of heart failure exacerbation.

Choice B rationale:

Decreased thirst is not a typical manifestation of heart failure. In fact, patients with heart failure often experience increased thirst due to fluid shifts and increased blood volume, leading to increased urine output and dehydration.

Choice C rationale:

Poor skin turgor is not a specific manifestation of heart failure. Skin turgor is commonly assessed to determine hydration status, but it is not directly related to heart failure.

Choice D rationale:

Tachycardia (rapid heart rate) is a common manifestation of heart failure. The heart beats faster to compensate for its decreased pumping efficiency. Tachycardia helps maintain cardiac output, but it is not a primary cause of heart failure; instead, it is a physiological response to the condition.
