Which maternal condition always necessitates delivery by cesarean birth?

Correct Answer: B

Rationale: The correct answer is B: Total placenta previa. In this condition, the placenta completely covers the cervix, posing a risk of severe bleeding during vaginal delivery. Cesarean birth is necessary to avoid potential life-threatening complications for both the mother and the baby. Partial abruptio placentae (choice A) involves premature separation of the placenta, but it doesn't always require a cesarean birth. Ectopic pregnancy (choice C) occurs when the fertilized egg implants outside the uterus, typically requiring surgical intervention but not always a cesarean birth. Eclampsia (choice D) is a serious condition characterized by high blood pressure and seizures, but it doesn't always necessitate cesarean birth unless there are other complications that require it.

Correct Answer: C

Rationale: The correct answer is C because folic acid is crucial in preventing neural tube defects and anemia in the developing fetus. The nurse should teach the expectant mother about the importance of taking folic acid supplements before and during pregnancy. Folic acid is essential for proper cell division and growth, reducing the risk of birth defects. Choice A is incorrect because calcium intake is important throughout pregnancy, not just in the first trimester. Choice B is incorrect as protein intake should be adequate to support maternal and fetal growth, not decreased. Choice D is incorrect as excessive intake of vitamins and minerals can be harmful to the mother and the baby. In summary, the expectant mother should be educated on the importance of folic acid supplementation to prevent birth defects and anemia, while also ensuring a balanced diet with all essential nutrients.

Correct Answer: A

Rationale: Rationale: 1. Insulin needs change during pregnancy due to hormonal changes. 2. During the first trimester, insulin needs may decrease. 3. During the second and third trimesters, insulin needs increase. 4. Postpartum, insulin needs return to pre-pregnancy levels. Therefore, choice A is correct as insulin needs vary based on gestational stage. Choices B, C, and D are incorrect because insulin needs do not uniformly increase or decrease throughout pregnancy or due to fetal insulin production.

Correct Answer: D

Rationale: Correct Answer: D - The patient should also be treated for chlamydia. Rationale: 1. Gonorrhea and chlamydia often coexist, so it is crucial to treat both infections to prevent complications. 2. Treating only gonorrhea may not fully resolve the patient's symptoms or prevent reinfection. 3. Dual therapy for gonorrhea and chlamydia is recommended to ensure optimal care for the patient. Summary of Incorrect Choices: A: The patient may benefit from oral contraceptives - This is not directly related to the treatment of gonorrhea. B: The patient must avoid use of tampons - This is not a standard recommendation for managing gonorrhea. C: The patient is susceptible to urinary incontinence - This is not a typical complication of gonorrhea.

Correct Answer: C

Rationale: The correct answer is C because it accurately explains the physiological change in the eye that leads to the need for bifocals. As individuals age, there is a gradual thickening of the lens of the eye, which affects the eye's ability to accommodate for near vision. This thickening makes it harder for the eye to focus on close objects, necessitating the use of bifocals to correct this near vision issue. Choices A, B, and D are incorrect because they do not provide a scientifically accurate explanation for the need for bifocals in older individuals. Option A is dismissive and does not address the specific change in the eye that leads to the need for bifocals. Option B implies aging as a general concept without specifying the relevant change in the eye. Option D incorrectly states that the eye gets shorter as we age, which is not the reason for needing bifocals.

Correct Answer: C

Rationale: Step 1: After mastoid surgery, patients may experience pain and dizziness, hence addressing the safe use of analgesics and antivertiginous agents is crucial for symptom management. Step 2: Analgesics help in managing post-operative pain, while antivertiginous agents help control dizziness, reducing the risk of falls. Step 3: Educating the patient on safe use ensures proper pain and symptom management, preventing complications. Step 4: Other choices are incorrect as they do not directly address immediate post-operative care needs such as pain and dizziness management.

Correct Answer: C

Rationale: The correct answer is C: "You are anxious about the surgery. Do you see smoking as helping?" This response acknowledges the patient's anxiety and invites him to explore his reasons for wanting to smoke, opening up a dialogue and potentially uncovering underlying issues. It also avoids judgment or direct orders, fostering a therapeutic nurse-patient relationship. Explanation of why the other choices are incorrect: A: "Smoking is the reason you are here." - This response is blaming and may increase the patient's guilt or anxiety, hindering effective communication. B: "The doctor left orders for you not to smoke." - This response is authoritative and may lead to resistance or defensiveness from the patient, rather than addressing his concerns. D: "Smoking is OK right now, but after your surgery it is contraindicated." - This response is unclear and may send mixed messages to the patient, potentially leading to confusion or misunderstanding.

Correct Answer: B

Rationale: The nurse sitting at the patient's bedside is using the personal zone of personal space, which ranges from 18 inches to 4 feet. This distance allows for a close interaction suitable for taking a nursing history while maintaining a professional yet personal connection. The socio-consultative zone (A) is 4-12 feet, more appropriate for professional interactions. The intimate zone (C) is 0-18 inches, too close for an initial nursing history. The public zone (D) is 12 feet or more, too distant for a personal conversation.

Correct Answer: D

Rationale: The correct answer is D, which is to arrange a referral to a community-based support program. This option is the most appropriate because it offers the patient ongoing support from individuals who understand what she is going through. Community-based support programs can provide a safe space for the patient to share her feelings, connect with others in similar situations, and access additional resources for coping. This intervention focuses on providing the patient with adequate support beyond the immediate recovery period, which is crucial for long-term coping and adjustment. Option A is incorrect as it may not consider the patient's individual needs for support beyond her spouse or partner. Option B may be premature as the patient might need time to process her diagnosis and surgery before moving on to the next phase of treatment. Option C may put undue pressure on the patient to maintain a specific emotional state for the sake of others, which may not be beneficial for her own coping and healing process.
