At what age are yearly mammograms recommended to start?

Correct Answer: B

Rationale: The correct answer is B. The American Cancer Society recommends yearly mammograms starting at age 40 and continuing for as long as a woman is in good health. Clinical breast examination should be done about every 3 years for women in their 20s and 30s and every year for women age 40 and older. Women should know how their breasts normally look and feel and report any breast change promptly to the healthcare provider. Breast self-examination should be done monthly starting when a woman is in her 20s. Choice A is incorrect as mammograms are not recommended to start at age 25. Choice C is incorrect as yearly mammograms are still recommended even without a family history of breast cancer. Choice D is incorrect as the recommended age for starting yearly mammograms is 40, not 20.

Correct Answer: D

Rationale: To assess tactile (vocal) fremitus, the nurse palpates the thorax and compares vibrations from side to side as the client repeats the word 'ninety-nine.' This technique helps in evaluating the intensity and symmetry of vibrations felt. Palpating for symmetric chest expansion involves assessing the expansion of the chest during breathing by placing hands on the anterolateral wall. Auscultating the breath sounds over the trachea and larynx is done to assess bronchial breath sounds, while auscultating over the peripheral lung fields is used to assess vesicular breath sounds.

Correct Answer: D

Rationale: The correct answer is hepatitis A. DTaP, MMR, and Hib are all part of the regular schedule of immunizations for children to protect them against diseases like diphtheria, tetanus, pertussis, measles, mumps, rubella, and Haemophilus influenzae type b. Hepatitis A vaccine is not included in the routine childhood immunization schedule but may be recommended in certain situations or regions where the disease is more prevalent. Hepatitis A is generally considered an optional vaccine for children but can be administered based on specific risk factors or regional guidelines.

Correct Answer: C

Rationale: The blood glucose level for a newborn infant should remain greater than 40 mg/dL to prevent permanent brain damage. When dealing with low blood glucose in a newborn, the most appropriate initial action is to contact the registered nurse. The nurse will obtain prescriptions regarding feeding the infant with low blood glucose and follow agency policies on feeding infants in such conditions. It is common practice to feed the infant if the glucose level is 40 mg/dL or less. Asking the registered nurse to draw another blood sample in 2 hours and repeating the test is not the most appropriate immediate action, as timely intervention is crucial in this situation. Contacting the healthcare provider may cause unnecessary delays since the registered nurse is usually the first point of contact for immediate actions in this scenario. Documenting the results in the newborn's medical record is essential, but it is not the initial step in managing low blood glucose in a newborn.

Correct Answer: B

Rationale: To alleviate nausea and vomiting, the client should avoid drinking liquids with meals. The client should keep dry crackers at her bedside, avoid fried foods, and eat smaller meals. Additionally, the client should eat dry crackers every 2 hours to prevent an empty stomach and avoid spicy foods and foods with strong odors, such as onion and cabbage. The incorrect choices are: A) Eating five or six small meals a day instead of three full meals is a correct recommendation. C) Keeping dry crackers at her bedside and eating them before getting out of bed in the morning is a helpful suggestion. D) Avoiding fried or greasy foods is a valid advice to alleviate nausea and vomiting.

Correct Answer: B

Rationale: When variable decelerations on the fetal heart rate monitor strip suggest cord compression, the immediate action the nurse should take is to reposition the mother to alleviate the compression. Elevating the mother's hips or changing her position can help shift the fetal presenting part and relieve pressure on the cord. This action aims to improve or resolve the variable decelerations. Contacting the registered nurse may be necessary, but it is not the immediate action required in this situation. Performing a vaginal examination is contraindicated due to the potential risk of further compromising blood flow through the umbilical cord. Inserting a gloved finger into the mother's vagina to feel for the cord is also not recommended as it poses a similar risk of exacerbating the situation.

Correct Answer: C

Rationale: The correct answer is midway between the symphysis pubis and the umbilicus. Immediately after delivery, the uterus is about the size of a large grapefruit or softball. The fundus can be palpated at this location but then rises to a level just above the umbilicus before sinking to the level of the umbilicus, where it remains for about 24 hours. After 24 hours, the fundus starts descending gradually. By the 10th to 14th day, the fundus is in the pelvic cavity and cannot be palpated abdominally. Choices A and B are incorrect as the fundus is not initially at the level of the umbilicus or 2 centimeters above it. Choice D is also incorrect as the fundus does not remain in the pelvic cavity immediately after delivery.

Correct Answer: A

Rationale: When a nurse notes accelerations from the baseline rate of the fetal heart rate, particularly when they occur with fetal movement, it is considered a reassuring sign. This indicates a healthy response to fetal activity. Reassuring signs in FHR monitoring include an average rate between 120 and 160 beats/min at term, a regular rhythm with slight fluctuations, accelerations from the baseline rate (often associated with fetal movement), and the absence of decreases from the baseline rate. Choices B, C, and D are incorrect because accelerations in FHR with fetal movement are not indicative of the need to contact the physician, fetal distress, or a nonreassuring sign. These signs would typically be associated with other abnormal FHR patterns that would warrant further assessment and intervention.

Correct Answer: B

Rationale: When late decelerations are noted on the fetal heart rate (FHR) monitor during oxytocin infusion, it indicates decreased oxygenation to the fetus. The immediate action the nurse should take is to stop the oxytocin infusion. This helps reduce uterine activity, increase fetal oxygenation, and prevent further stress on the fetus. Stopping the oxytocin infusion is crucial to address the underlying issue causing the late decelerations. Checking the woman's blood pressure and pulse, increasing the IV rate of the nonadditive solution, or notifying the healthcare provider can be important actions but are secondary to stopping the oxytocin infusion in this scenario.
