Correct Answer: C

Rationale: After delivery, bradycardia (pulse rate 50-70 beats/min) may occur, reflecting the large amount of blood returning to the central circulation after delivery of the placenta. The increase in central circulation results in increased stroke volume, allowing a slower heart rate to provide adequate maternal circulation. A pulse rate of 55 beats/min falls within the normal range post-delivery, so there is no need to notify the healthcare provider immediately. It is important for the client to remain on bed rest in the immediate postpartum period to prevent complications. While range-of-motion exercises are beneficial for a client on bed rest, it is not the priority based on the data provided. Therefore, the most appropriate nursing action is to document the finding for accurate record-keeping and monitoring of the client's condition.

Correct Answer: B

Rationale: Melena' is the term used to describe abnormal black tarry stool that has a distinctive odor and contains digested blood. It usually results from bleeding in the upper gastrointestinal tract and is often a sign of peptic ulcer disease or small bowel disease. The presence of melena is detected by checking the client's stool for blood. Blood in the client's urine, decreased urine output, and diarrhea are not associated with the assessment for melena.

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: B

Rationale: The nurse expects to primarily note tympany when percussing the abdomen. Tympany should predominate because air in the intestines rises to the surface when the client is in a supine position. Dullness is usually heard over a distended bladder, adipose tissue, fluid, or a mass. Borborygmus, which refers to hyperperistalsis, is typically heard on auscultation, not percussion. Hyperresonance is present with gaseous distention, not the typical finding when percussing all four quadrants of the abdomen.

Correct Answer: B

Rationale: The chest circumference of the infant is measured at the level of the nipples. It is usually 2 to 3 cm smaller than the head circumference. The average chest circumference is 30.5 to 33 cm (12-13 inches). When there is molding of the head, the head and chest measurements may be equal at birth. Placing the tape measure at the level of the nipples ensures accuracy and consistency in newborn assessment. Options A, C, and D are incorrect as the chest circumference is specifically measured at the level of the nipples to obtain precise measurements.
