A nurse is preparing to administer methylphenidate 7.5 mg PO to a school-age child who has ADHD. The amount available is methylphenidate oral solution 5 mg/5 mL. How many mL of the medication should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero)
The Correct Answer is ["7.5"]
Calculation:
Desired dose = 7.5 mg
Available concentration = 5 mg / 5 mL
= 1 mg/mL
Calculate the volume to administer:
Volume to administer (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 7.5 mg / 1 mg/mL
= 7.5 mL

Correct Answer is A
Explanation
A. Drink high-protein nutritional supplements between meals: Clients with COPD often experience anorexia due to fatigue, difficulty breathing while eating, and early satiety. High-protein, high-calorie supplements between meals help meet nutritional needs without overwhelming them during main meals, supporting energy levels and respiratory muscle strength.
B. Eat more hot foods than cold foods at mealtime: Hot foods can produce stronger odors that may worsen appetite loss. Cold foods tend to have milder smells and may be better tolerated by clients with anorexia, making cold foods preferable rather than focusing on hot foods.
C. Eat low-calorie foods first at mealtime: Clients with anorexia and COPD should prioritize high-calorie, nutrient-dense foods first to maximize intake before feeling full. Eating low-calorie foods first could reduce overall calorie intake, worsening weight loss and malnutrition risks.
D. Increase liquids during meals: Consuming large amounts of liquid during meals can cause early satiety, making it harder for clients to consume enough food. It is better to encourage drinking fluids between meals to optimize food intake during eating times.
Correct Answer is A
Explanation
A. "I really wish I had a girl instead.": Expressing disappointment in the baby's gender may indicate difficulty bonding with the infant or potential postpartum emotional concerns. This statement warrants further evaluation to assess for postpartum depression or attachment issues.
B. "I am so relieved the baby looks like my mother.": Feeling relieved that the baby resembles a family member is a normal emotional reaction and does not typically require further psychological evaluation unless associated with more concerning behaviors.
C. "My labor was so long I'm glad it's over.": Expressing relief after a long labor is a normal reaction and does not indicate emotional distress or dysfunction that would need further mental health evaluation.
D. "My appetite has really increased.": An increased appetite two weeks postpartum is a normal physiological response as the body recovers from childbirth, particularly if the client is breastfeeding. It does not suggest a need for further emotional or physical evaluation.
