A nurse is planning care for a child who has mumps. Which of the following instructions should the nurse include in the plan?

Choice A reason: This choice is incorrect because the radial artery is not an ideal site to assess the heart rate in an infant. The radial artery is located on the thumb side of the wrist, and it can be palpated by placing two fingers over it. It may be used for adults or older children who have a strong pulse, but it may be difficult to locate or feel in an infant who has a small or weak pulse.

Choice B reason: This choice is incorrect because the carotid artery is not an ideal site to assess the heart rate in an infant. The carotid artery is located on either side of the neck, and it can be palpated by placing two fingers over it. It may be used for adults or older children who have a cardiac arrest or shock, but it may be risky to use in an infant who has a fragile neck or airway.

Choice C reason: This choice is incorrect because the brachial artery is not an ideal site to assess the heart rate in an infant. The brachial artery is located on the inner side of the upper arm, and it can be palpated by placing two fingers over it. It may be used for infants or young children who have a blood pressure measurement, but it may be uncomfortable or inaccurate to use for a heart rate assessment.

Choice D reason: This choice is correct because the apex of the heart is an ideal site to assess the heart rate in an infant. The apex of the heart is located at the fifth intercostal space on the left midclavicular line, and it can be auscultated by placing a stethoscope over it. It may be used for infants or young children who have a regular and strong heartbeat, and it may provide the most accurate measurement of the heart rate.

Choice A reason: This choice is correct because a child who has nephrotic syndrome is the most appropriate roommate for a child who has leukemia. Nephrotic syndrome is a kidney disorder that causes proteinuria, edema, hypoalbuminemia, and hyperlipidemia. It does not pose any risk of infection or injury to the child who has leukemia, and it does not require any isolation or special precautions. Therefore, placing these two children in the same room can help to conserve resources and promote socialization.

Choice B reason: This choice is incorrect because a child recovering from a ruptured appendix is not an appropriate roommate for a child who has leukemia. A ruptured appendix is a medical emergency that occurs when the appendix becomes inflamed and bursts, releasing bacteria and pus into the abdominal cavity. It may cause peritonitis, sepsis, or abscess formation, and it requires surgery and antibiotics. It may pose a risk of infection to a child who has leukemia, who has a weakened immune system due to chemotherapy or bone marrow suppression. Therefore, placing these two children in the same room can increase the chance of cross-contamination and complications.

Choice C reason: This choice is incorrect because a child who has rheumatic fever is not an appropriate roommate for a child who has leukemia. Rheumatic fever is an inflammatory disease that occurs as a complication of streptococcal infection, such as strep throat or scarlet fever. It may affect the heart, joints, skin, or nervous system, and it requires anti-inflammatory and antibiotic medications. It may pose a risk of infection to the child who has leukemia, who has a compromised immune system due to cancer or treatment. Therefore, placing these two children in the same room can increase the likelihood of transmission and infection.

Choice D reason: This choice is incorrect because a child who has cystic fibrosis is not an appropriate roommate for a child who has leukemia. Cystic fibrosis is a genetic disorder that affects the mucus glands of the lungs, pancreas, liver, intestines, and reproductive organs. It causes thick and sticky mucus to build up in the organs, leading to chronic lung infections, pancreatic insufficiency, malnutrition, and infertility. It requires respiratory therapy, enzyme supplements, nutritional support, and antibiotics. It may pose a risk of infection to the child who has leukemia, who has a reduced ability to fight germs due to malignancy or therapy. Therefore, placing these two children in the same room can increase the possibility of exposure and infection.
