Multifetal pregnancies with triplets occur at a rate of 1 in 8,100 births, but twins occur much more frequently with a rate of:
- A. 1 in 85 births.
- B. 1 in 5400 births.
- C. 1 in 2700 births.
- D. 1 in 540 births
Correct Answer: A
Rationale: The correct answer is A: 1 in 85 births. The rate of twin pregnancies is approximately 1 in 85 births. This means that twins are more common compared to triplets, which occur at a rate of 1 in 8,100 births. Choices B, C, and D are incorrect because they do not reflect the correct frequency of twin pregnancies as stated in the question.

Rotating injection sites when administering insulin prevents which of the following complications?
- A. Insulin edema
- B. Insulin lipodystrophy
- C. Insulin resistance
- D. Systemic allergic reactions
Correct Answer: B
Rationale: Rotating injection sites when administering insulin helps prevent insulin lipodystrophy, which is the abnormal distribution of fat at injection sites. Insulin edema (choice A) is not prevented by rotating injection sites; it is characterized by swelling at the site of insulin injection due to increased capillary permeability. Insulin resistance (choice C) is a condition where the body's cells become less responsive to insulin, and rotating injection sites does not directly prevent this. Systemic allergic reactions (choice D) are not specifically prevented by rotating injection sites; they are related to an allergic response to insulin.
In which position will you place your patient when they are demonstrating the signs and symptoms of hypovolemic shock?
- A. The Trendelenburg position
- B. The supine position
- C. The left lateral position
- D. The right lateral position
Correct Answer: A
Rationale: The correct answer is A, the Trendelenburg position. This position involves placing the patient with their legs elevated higher than their head. It is used to increase blood flow to the upper body, including the brain and heart, in cases of hypovolemic shock. This helps improve perfusion to vital organs. Choices B, C, and D are incorrect as they do not facilitate the desired redistribution of blood flow needed in hypovolemic shock. The supine position is lying flat on the back, the left lateral position is lying on the left side, and the right lateral position is lying on the right side.
Which preventive measure can be employed to decrease the risk of compartment syndrome?
- A. The administration of a potassium-sparing diuretic for heart failure
- B. A bivalve cast for a skeletal fracture
- C. A cerebral diuretic to decrease intracranial pressure after a head injury
- D. A chest tube to restore normal intrathoracic pressure after a pneumothorax
Correct Answer: B
Rationale: The correct answer is B. A bivalve cast can help decrease the risk of compartment syndrome by providing space for swelling, thus preventing the build-up of pressure within the muscles. Choices A, C, and D are incorrect because they are not directly related to preventing compartment syndrome. Choice A is more focused on managing heart failure, choice C on reducing intracranial pressure, and choice D on restoring intrathoracic pressure after a pneumothorax, which are not relevant to preventing compartment syndrome.
You are performing a neurological assessment of your adolescent patient. The patient has the Moro reflex. How should you interpret this neurological assessment finding?
- A. It is normal among adolescents.
- B. It indicates that the patient has an intact peripheral nervous system.
- C. It indicates that the patient has an intact central nervous system.
- D. It is not a normal finding.
Correct Answer: D
Rationale: The Moro reflex, also known as the startle reflex, is typically present in infants up to around 4-6 months of age and is characterized by the infant's response to a sudden loss of support or loud noise. It is not a normal finding in adolescents or older individuals. Therefore, if an adolescent patient exhibits the Moro reflex during a neurological assessment, it is considered abnormal and warrants further evaluation. Choices A, B, and C are incorrect because the Moro reflex is not expected or normal among adolescents and does not specifically indicate the status of either the peripheral or central nervous system in this age group.
A nurse is supervising an assistive personnel (AP) who is feeding a client who has dysphagia. Which of the following actions by the AP should the nurse identify as correct technique?
- A. Elevating the head of the client's bed to 30 degrees during mealtime
- B. Withholding fluids until the end of the meal
- C. Providing a 10-minute rest period prior to meals
- D. Instructing the client to place her chin toward her chest when swallowing
Correct Answer: D
Rationale: The correct technique for a client with dysphagia is to instruct them to place their chin toward their chest when swallowing. This action helps to close off the airway during swallowing, reducing the risk of aspiration. Elevating the head of the client's bed to 30 degrees during mealtime helps prevent aspiration, but this is not the responsibility of the AP. Withholding fluids until the end of the meal can lead to dehydration and is not a recommended practice. Providing a 10-minute rest period prior to meals is not specifically related to improving swallowing safety for clients with dysphagia.
