Pulses can be graded according to certain criteria. Which is a description of a normal pulse?

Correct Answer: B

Rationale: In grading pulses, the normal pulse is typically designated as +1. This indicates a pulse that is easily felt, normal in strength, and corresponds to a healthy pulse rate. A +1 pulse is considered regular, not too weak or too strong, and is indicative of good cardiovascular health. Any abnormalities in pulse strength or rate would be graded differently.

Correct Answer: B

Rationale: Anemia is a condition characterized by a low red blood cell count or insufficient hemoglobin levels, resulting in decreased oxygen-carrying capacity in the blood. One of the nursing interventions for anemia is to promote a high protein, vitamin, and iron diet. Iron is essential for the production of hemoglobin, which carries oxygen in the blood. Including foods rich in iron, such as lean meats, dark leafy greens, beans, and fortified cereals, can help boost iron levels in the body. Additionally, consuming foods high in vitamin C can also aid in iron absorption. Protein is crucial for overall health and plays a role in red blood cell production. By encouraging a nutrient-rich diet, nurses can help support the body's ability to replenish its red blood cell supply and improve the symptoms associated with anemia.

Correct Answer: D

Rationale: The correct information that the nurse should include in the teaching is that clothing should always fit loosely over the harness. This is important to prevent restriction of movement and ensure comfort for the child wearing the Pavlik harness. Tight clothing can cause discomfort, skin irritation, and interfere with the effectiveness of the harness in positioning the hip properly. Parents should be advised to choose clothing that is loose-fitting and does not put pressure on the harness or the child's skin.

Correct Answer: D

Rationale: Streptococcus viridans is the most common causative agent of bacterial endocarditis. This group of bacteria consists of various species, including S. sanguinis and S. mutans, which normally reside in the oral cavity and are commonly associated with endocarditis following dental procedures. Streptococcus viridans can enter the bloodstream due to dental work, oral infections, or trauma to the oral tissues, and cause infective endocarditis by adhering to damaged heart valves or endocardium. Staphylococcus aureus and Enterococcus species are other common pathogens associated with endocarditis, but Streptococcus viridans remains the most prevalent causative agent.

Correct Answer: A
