A nurse is collecting data from a client who has placenta previa. Which of the following findings should the nurse expect?
Increased fetal movement
Persistent uterine contractions
Rigid abdomen
Bright red vaginal bleeding
The Correct Answer is D
Bright red vaginal bleeding
Placenta previa is a condition in which the placenta partially or completely covers the opening of the cervix. One of the hallmark findings of placenta previa is painless, bright red vaginal bleeding, typically occurring in the later stages of pregnancy. This bleeding can be sudden and heavy or intermittent. It is important for the nurse to recognize this sign and promptly report it to the healthcare provider.
Increased fetal movement in (option A) is incorrect: Fetal movement is not directly related to placenta previa and may vary depending on the individual fetus.
Persistent uterine contractions in (option B): Persistent uterine contractions are more commonly associated with conditions such as preterm labour or uterine irritability, rather than placenta previa.
Rigid abdomen in (option C): A rigid abdomen may indicate uterine hypertonus or other complications, but it is not a specific finding of placenta previa.

Explanation
Hyperkalemia refers to an elevated level of potassium in the blood. It can have various manifestations, and one of the critical effects of hyperkalemia is its impact on cardiac function. High levels of potassium can disrupt the normal electrical conduction in the heart, leading to arrhythmias or irregular heart rate. These arrhythmias can range from mild palpitations to more severe and life-threatening conditions like ventricular fibrillation.
Dry mucous membranes are more commonly associated with dehydration or reduced fluid intake. Hyperkalemia does not directly cause dry mucous membranes.
Trousseau's sign is a clinical manifestation of hypocalcemia, not hyperkalemia. It is characterized by carpal spasms induced by inflating a blood pressure cuff above the client's systolic blood pressure for a few minutes.
Hyperactive reflexes are commonly seen in conditions such as hyperthyroidism or certain neurologic disorders. They are not directly related to hyperkalemia.
Correct Answer is A
Explanation
Epinephrine is a medication that belongs to a class of drugs called adrenergic agonists. It works by stimulating certain receptors in the body, particularly alpha and beta adrenergic receptors.
One of the effects of epinephrine is vasoconstriction, which can help reduce swelling and inflammation.
Swelling of the lips, also known as angioedema, can occur as an allergic reaction to certain substances, such as foods, medications, or insect bites. Epinephrine acts as an immediate treatment for severe allergic reactions, including angioedema, by constricting blood vessels and reducing swelling.
The other manifestations mentioned, such as hyperglycemia (high blood sugar), hand tremors, and nausea, are not typically treated with epinephrine. Epinephrine's primary role is to address severe allergic reactions, anaphylaxis, or potentially life-threatening conditions associated with allergic responses
