A nurse is preparing to administer mannitol 0.2 g/kg IV bolus over 5 min as a test dose to a client who has severe oliguria. The client weighs 198 lb. What is the amount in grams the nurse should administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

• A is incorrect because assessing the apical pulse while the newborn is crying can result in an inaccurate measurement due to increased heart rate and respiratory rate.
• B is incorrect because palpating the radial pulse for 30 seconds is not appropriate for a newborn as it can be difficult to locate and count accurately.
• C is incorrect because listening to the apical pulse while palpating the radial pulse is not necessary for a newborn and can be confusing and time-consuming.
• D is correct because auscultating the apical pulse at least 1 min is the best way to assess a newborn's heart rate as it provides an accurate and reliable measurement.

Choice A rationale:

A child who has mononucleosis and reports severe fatigue requires medical attention, but this condition does not pose an immediate life-threatening risk compared to acute epiglottitis. Mononucleosis is a viral infection that can cause fatigue, sore throat, and swollen lymph nodes. While the child should be assessed, the priority is given to the child with acute epiglottitis due to the potential for airway obstruction and respiratory distress.

Choice B rationale:

A child who has Wilms' tumor and an abdominal mass also needs urgent medical evaluation. Wilms' tumor is a rare kidney cancer that primarily affects children. While it requires prompt attention, acute epiglottitis poses a more immediate threat to the airway and breathing.

Choice C rationale:

A child with acute epiglottitis and drooling requires immediate assessment and intervention. Acute epiglottitis is a potentially life-threatening infection that can cause severe swelling of the epiglottis, leading to airway obstruction. The child may have difficulty breathing and may present with the classic drooling sign due to the inability to swallow saliva. Prompt medical intervention, including airway management and appropriate antibiotics, is essential in this situation.

Choice D rationale:

A child with a urinary tract infection and bright red blood in her urine requires medical evaluation, but this condition is not as urgent as acute epiglottitis. Hematuria (blood in the urine) can have various causes, including urinary tract infections or kidney stones. While the child should receive medical attention, it does not take precedence over the immediate threat posed by acute epiglottitis, which requires urgent intervention to maintain the airway.
