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: During the fourth stage of labor, the woman's vital signs should be assessed every 15 minutes during the first hour. An increasing pulse rate is an early sign of excessive blood loss, as the heart beats faster to compensate for reduced blood volume. The blood pressure decreases as blood volume diminishes, but this is a later sign of hypovolemia. The most common reason for excessive postpartum bleeding is a uterus that is not firmly contracting and compressing open vessels at the placental site. Therefore, the nurse should check the client's uterine fundus for firmness, height, and positioning. Checking the uterine fundus is the priority action as it helps determine if the client is bleeding excessively. Notifying the registered nurse immediately is not necessary unless the cause of bleeding is unclear and needs further intervention. Continuing to check vital signs without addressing the potential issue will delay necessary intervention. Documenting findings is important, but not the immediate priority when faced with a potential emergency situation like postpartum hemorrhage.

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: Vitamin K is administered to newborn infants to help prevent hemorrhagic disease. The best site for intramuscular injection in infants is the vastus lateralis muscle. This site is preferred due to its location away from the sciatic nerve, femoral artery, and vein, reducing the risk of complications. The rectus femoris muscle may be used if necessary; however, it is less favorable than the vastus lateralis due to its proximity to vital structures, making injections there more hazardous. The deltoid muscle is not typically used for IM injections in newborns. The gluteal muscles should be avoided until the child has been walking for at least a year, as they are poorly developed and close to the sciatic nerve.

Correct Answer: D

Rationale: Amniotic fluid should be clear and may include bits of vernix, the creamy white fetal skin lubricant. Therefore, the nurse would most appropriately document the findings. Checking the client's temperature, reporting the findings to the nurse-midwife, and obtaining a sample of the amniotic fluid for laboratory analysis are not necessary in this situation. Cloudy, yellow, or foul-smelling amniotic fluid suggests infection, while green fluid indicates that the fetus passed meconium before birth. If abnormalities are noted, the nurse should notify the nurse-midwife.
