A nurse in a provider's office is caring for a client who is at 34 weeks of gestation and at risk for placental abruption. The nurse should recognize that which of the following is the most common risk factor for abruption?

Blunt force trauma

Hypertension

Gestational diabetes mellitus

Cigarette smoking

Answer and Explanation

The Correct Answer is B

Choice A reason: Blunt force trauma is a possible risk factor for placental abruption, which is a condition where the placenta detaches from the uterine wall and causes bleeding, pain, and fetal distress. However, blunt force trauma is not the most common risk factor, as it accounts for only a small percentage of cases. The most common causes of blunt force trauma are motor vehicle accidents, falls, or domestic violence.

Choice B reason: Hypertension is the most common risk factor for placental abruption, as it affects about 50% of cases. Hypertension can cause vasospasm and reduced blood flow to the placenta, which can weaken the attachment and lead to separation. Hypertension can be chronic, gestational, or related to preeclampsia.

Choice C reason: Gestational diabetes mellitus is not a risk factor for placental abruption, but rather a condition where the client develops high blood sugar levels during pregnancy and can cause complications, such as macrosomia, polyhydramnios, or neonatal hypoglycemia. Gestational diabetes mellitus does not affect the placental attachment or function.

Choice D reason: Cigarette smoking is a risk factor for placental abruption, as it can cause vasoconstriction and reduced oxygen delivery to the placenta, which can impair its growth and development. However, cigarette smoking is not the most common risk factor, as it affects about 25% of cases.

Correct Answer is ["0.5"]

Explanation

To calculate the number of tablets, the nurse should use the following formula:

Number of tablets = (Desired dose / Available dose) x (Available form / Desired form)

In this case, the desired dose is 50 mg, the available dose is 100 mg, the available form is 1 tablet, and the desired form is 1 tablet. Therefore, the formula becomes:

Number of tablets = (50 mg / 100 mg) x (1 tablet / 1 tablet)

Number of tablets = 0.5 x 1

Number of tablets = 0.5

The nurse should round the answer to the nearest tenth, which is 0.5. The nurse should use a leading zero if the answer is less than 1, which is 0.5. The nurse should not use a trailing zero, which means 0.5 and not 0.50.

A. "Your baby needs this medication to fight a possible respiratory tract infection." B. "Surfactant is used to reduce episodes of periodic apnea." C. "Surfactant improves the ability of your baby's lungs to exchange oxygen and carbon dioxide." D. "The drug keeps your baby from requiring too much sedation."

Correct Answer is C

Explanation

Choice A reason: This statement is incorrect, as surfactant is not an antibiotic and does not treat infections. Surfactant is a substance that is naturally produced by the lungs to reduce the surface tension and prevent the alveoli from collapsing. Premature infants may have insufficient surfactant, which can cause RDS.

Choice B reason: This statement is partially true, as surfactant can help reduce episodes of periodic apnea, which is a condition where the newborn stops breathing for more than 20 seconds. However, this is not the main purpose of surfactant therapy, and other interventions, such as oxygen, ventilation, and caffeine, may be needed to treat apnea.

Choice C reason: This statement is correct, as surfactant improves the ability of the baby's lungs to exchange oxygen and carbon dioxide, which are essential for life. Surfactant therapy can improve the lung function, reduce the need for mechanical ventilation, and prevent complications, such as bronchopulmonary dysplasia and pulmonary hemorrhage.

Choice D reason: This statement is false, as surfactant does not affect the level of sedation in the newborn. Surfactant is administered through an endotracheal tube, which may require sedation to reduce discomfort and agitation. The nurse should monitor the newborn's vital signs, oxygen saturation, and pain level during and after the procedure.
