Nursing Elites

1. What is the primary purpose of a platelet count?

• A. Assessing clot formation potential
• B. Assessing bleeding risk
• C. Detecting antigen-antibody response
• D. Identifying cardiac enzymes presence

Correct answer: B

Rationale: A platelet count is primarily used to assess the risk of bleeding. Platelets play a crucial role in blood clotting, so a low platelet count can lead to an increased risk of bleeding. Monitoring platelet levels helps healthcare providers evaluate a patient's ability to form clots and manage bleeding.

2. Which hormone is secreted by the Islets of Langerhans?

• A. Progesterone
• B. Testosterone
• C. Insulin
• D. Hemoglobin

Correct answer: C

Rationale: Insulin is the correct answer. It is the hormone secreted by the Islets of Langerhans in the pancreas. These specialized cells regulate blood sugar levels by releasing insulin in response to high blood glucose levels. Insulin aids in glucose absorption by cells, lowering blood sugar levels. Progesterone, testosterone, and hemoglobin are not secreted by the Islets of Langerhans and do not play a role in blood sugar regulation.

3. The physician orders a platelet count to be performed on Mrs. Smith after breakfast. The nurse is responsible for:

• A. Instructing the patient about this diagnostic test
• B. Writing the order for this test
• C. Giving the patient breakfast
• D. All of the above

Correct answer: A

Rationale: The nurse's responsibility in this scenario is to instruct the patient about the diagnostic test ordered by the physician. This includes explaining the purpose of the test, any necessary preparations, and what to expect. The nurse is not responsible for writing the order, as this is the physician's role. Additionally, providing breakfast is not directly related to the platelet count test. Therefore, the correct answer is A, which aligns with the nurse's role in educating and supporting the patient regarding the test.

4. A client in labor is receiving oxytocin. Which of the following findings indicates that the nurse should increase the rate of infusion?

• A. Urine output of 20 ml/hr.
• B. Montevideo units constantly at 300 mm Hg.
• C. FHR pattern showing absent variability.
• D. Contractions occurring every 5 minutes and lasting 30 seconds.

Correct answer: B

Rationale: Montevideo units measure the strength and frequency of contractions during labor. A consistent Montevideo units reading of 300 mm Hg or higher is indicative of effective uterine contractions. In this scenario, an increase in the rate of oxytocin infusion may be warranted to further augment contractions and promote progress in labor. The other options, such as low urine output, absent variability in fetal heart rate, and short contractions, do not directly correlate with the need for an increase in oxytocin infusion rate.

5. During a seizure, what is the primary intervention?

• A. Protect the patient from injury
• B. Insert an airway
• C. Elevate the head of the bed
• D. Withdraw all pain medications

Correct answer: A

Rationale: The primary intervention during a seizure is to protect the patient from injury. This involves creating a safe environment by moving harmful objects away, cushioning the head, and staying with the patient until the seizure ends. Inserting an airway is only necessary if the patient's airway is obstructed, not routinely during a seizure. Elevating the head of the bed is not a priority during an active seizure as it won't affect the seizure's outcome. Withdrawing all pain medications is not a standard practice unless there are specific contraindications related to the seizure itself.
