The nurse is teaching a pregnant client how to distinguish prelabor contractions from true labor contractions. Which statement about prelabor contractions is accurate?

A. They are irregular

B. They are usually felt in the abdomen

C. They start in the back and radiate to the abdomen

D. They become more intense during walking

Correct Answer: B
Rationale: The correct statement about prelabor contractions (Braxton Hicks contractions) is that they are usually felt in the abdomen. They are irregular in nature and do not intensify with movement. Choice A is incorrect because prelabor contractions are irregular, not regular. Choice C is incorrect as prelabor contractions do not start in the back and radiate to the abdomen. Choice D is incorrect as prelabor contractions do not become more intense during walking.

A client with peripheral neuropathy due to cirrhosis is at risk for injury. What should the nurse do?

• A. Protect the client's feet from injury
• B. Apply a heating pad to the affected area
• C. Keep the client's feet elevated
• D. Assess the feet and legs for jaundice

Correct Answer: A
Rationale: Protecting the client's feet from injury is critical as peripheral neuropathy can lead to decreased sensation and increased risk of trauma. This measure helps prevent wounds, ulcers, and other complications. Applying a heating pad (Choice B) can worsen symptoms and cause burns due to decreased sensation. Keeping the client's feet elevated (Choice C) may help reduce swelling but does not directly address the risk of injury. Assessing for jaundice (Choice D) is important in cirrhosis but is not directly related to the client's risk of injury due to peripheral neuropathy.

Which cranial nerve is responsible for the sense of smell?

• A. Olfactory nerve
• B. Optic nerve
• C. Trigeminal nerve
• D. Vagus nerve

Correct Answer: A
Rationale: The olfactory nerve (Cranial Nerve I) is indeed responsible for the sense of smell. It is located in the nasal cavity and transmits olfactory information to the brain. The optic nerve (Choice B) is responsible for vision, the trigeminal nerve (Choice C) is responsible for sensation in the face, and the vagus nerve (Choice D) is responsible for various functions such as heart rate, digestion, and speech. Therefore, the correct answer is the olfactory nerve (Choice A).

A client who had a hip replacement is being prepared for discharge. What should the nurse include in the discharge teaching to prevent hip dislocation?

• A. Avoid crossing your legs at the knees or ankles.
• B. Do not sleep on the side of the hip that was operated on.
• C. Sit in high chairs and keep your knees higher than your hips.
• D. Do not bend forward at the waist to pick up objects.

Correct Answer: A
Rationale: The correct answer is A: 'Avoid crossing your legs at the knees or ankles.' Crossing legs at the knees or ankles can cause excessive stress on the new hip joint, leading to a risk of dislocation. Choice B is incorrect because sleeping on the side of the operated hip can also increase the risk of dislocation. Choice C is incorrect as sitting in low chairs with knees higher than hips is a recommended position to prevent hip dislocation. Choice D is incorrect because bending forward at the waist to pick up objects can strain the hip joint and increase the risk of dislocation.

Which type of cell is responsible for producing antibodies in the immune system?

• A. B lymphocytes
• B. T lymphocytes
• C. Macrophages
• D. Neutrophils

Correct Answer: A
Rationale: The correct answer is A: B lymphocytes. B lymphocytes (B cells) are a crucial part of the adaptive immune system. They produce antibodies, which are proteins that specifically target and neutralize pathogens such as bacteria and viruses. T lymphocytes (choice B) are involved in cell-mediated immunity rather than antibody production. Macrophages (choice C) are phagocytic cells that engulf and digest pathogens but do not produce antibodies. Neutrophils (choice D) are a type of white blood cell that primarily function in the innate immune response by phagocytosing pathogens.
