Nursing Elites

1. A healthcare provider is assessing a newborn who has a coarctation of the aorta. Which of the following should the provider recognize as a clinical manifestation of coarctation of the aorta?

• A. Increased blood pressure in the arms with decreased blood pressure in the legs
• B. Decreased blood pressure in the arms with increased blood pressure in the legs
• C. Increased blood pressure in both the arms and the legs
• D. Decreased blood pressure in both the arms and the legs

Correct answer: A

Rationale: The correct answer is increased blood pressure in the arms with decreased blood pressure in the legs. Coarctation of the aorta is a congenital heart defect characterized by a narrowing of the aorta, leading to increased blood pressure in the upper extremities and decreased blood pressure in the lower extremities due to decreased blood flow beyond the narrowing. Choice B is incorrect because coarctation of the aorta does not lead to increased blood pressure in the legs. Choice C is incorrect because increased blood pressure in both the arms and legs is not a typical manifestation of coarctation of the aorta. Choice D is incorrect because decreased blood pressure in both the arms and legs is not characteristic of coarctation of the aorta.

2. During preterm labor, a client is scheduled for an amniocentesis. The nurse should review which of the following tests to assess fetal lung maturity?

• A. Alpha-fetoprotein (AFP)
• B. Lecithin/sphingomyelin (L/S) ratio
• C. Kleihauer-Betke test
• D. Indirect Coombs' test

Correct answer: B

Rationale: The Lecithin/sphingomyelin (L/S) ratio is a test used to evaluate fetal lung maturity. An L/S ratio greater than 2:1 indicates fetal lung maturity. This test helps in determining the risk of respiratory distress syndrome in the newborn. Alpha-fetoprotein (AFP) is used in screening for neural tube defects, not for assessing lung maturity. The Kleihauer-Betke test is used to detect fetal-maternal hemorrhage, not fetal lung maturity. The Indirect Coombs' test is used to identify the presence of antibodies in the mother's blood that could attack fetal red blood cells, not for assessing lung maturity.

3. A healthcare professional is assisting with the care of a client who is receiving IV magnesium sulfate. Which of the following medications should the healthcare professional anticipate administering if magnesium sulfate toxicity is suspected?

• A. Nifedipine
• B. Pyridoxine
• C. Ferrous sulfate
• D. Calcium gluconate

Correct answer: D

Rationale: Calcium gluconate is the antidote for magnesium sulfate toxicity. In cases of magnesium sulfate toxicity, calcium gluconate is administered to counteract the effects of magnesium and restore calcium levels. Magnesium toxicity can lead to symptoms such as muscle weakness, respiratory depression, and cardiac arrhythmias. Calcium gluconate helps in reversing these effects by competing with magnesium and preventing its adverse manifestations. Nifedipine is a calcium channel blocker used for conditions like hypertension and angina, not for magnesium toxicity. Pyridoxine is vitamin B6 and is not the antidote for magnesium toxicity. Ferrous sulfate is an iron supplement and is not used to treat magnesium sulfate toxicity.

4. A client at 38 weeks of gestation with a diagnosis of preeclampsia has the following findings. Which of the following should the nurse identify as inconsistent with preeclampsia?

• A. 1+ pitting sacral edema
• B. 3+ protein in the urine
• C. Blood pressure 148/98 mm Hg
• D. Deep tendon reflexes of +1

Correct answer: D

Rationale: Deep tendon reflexes of +1 are inconsistent with preeclampsia. Preeclampsia typically presents with hyperreflexia, not diminished reflexes. Diminished reflexes may indicate other neurological conditions, thus making this finding inconsistent with preeclampsia. Choices A, B, and C are consistent with preeclampsia. Pitting sacral edema, protein in the urine, and elevated blood pressure are common findings in preeclampsia due to fluid retention, kidney involvement, and hypertension associated with the condition.

5. A client presents with uterine hypotonicity and postpartum hemorrhage. Which action should the nurse prioritize?

• A. Check the client's capillary refill.
• B. Massage the client's fundus.
• C. Insert an indwelling urinary catheter for the client.
• D. Prepare the client for a blood transfusion.

Correct answer: B

Rationale: In a client with uterine hypotonicity and postpartum hemorrhage, the priority is to address the risk of hypovolemic shock, which can lead to vital organ perfusion compromise and potentially death. Massaging the client's fundus helps to control bleeding by promoting uterine contraction and reducing blood loss, making it the nurse's priority intervention in this situation. Checking capillary refill may be important in assessing perfusion status but is not the priority over controlling the hemorrhage. Inserting an indwelling urinary catheter is not the priority in managing postpartum hemorrhage. Although preparing for a blood transfusion may be necessary, addressing the primary cause of bleeding by massaging the fundus takes precedence to stabilize the client's condition.
