Case Study 10.1.1 §10.1 source ↗

Read the following clinical scenario and then answer the questions that follow. This case study will evolve throughout the chapter.

The nurse prepares to assess Catalina for more details about her past medical history and current health concerns. Catalina reports that prior to the past few months, she had felt great and had managed her grades and social life well. She does not take any medications regularly, including daily vitamins. Her mother confirms that she has no significant past medical issues, which makes her current symptoms more concerning. Catalina never complains and has always prioritized her grades. Catalina and her mother confirm that nothing has changed in their social circumstances, and Catalina denies symptoms of depression.

The nurse is aware that adolescent females are at risk for anemia and ID once menstruation begins and therefore takes a detailed menstrual bleeding history. Catalina reports that she has had regular menstrual cycles lasting 5–7 days since age 13 years but has noticed an increase in the heaviness of her flow this school year. She further says that her use of sanitary pads has increased, and she must change her pad every 1–2 hours during the day and night. The nurse recognizes this as a sign of heavy menstrual bleeding and notifies the health care provider of her concern that Catalina may be anemic and iron deficient.

What is an expected dose of oral iron supplement for Catalina?
  1. a.
    3 mg/kg/dose twice daily for 3 months
  2. b.
    6 mg/kg/dose twice daily for 3 months
  3. c.
    3–6 mg/kg/day for 6 months
  4. d.
    3 mg/kg/day until anemia is resolved

Answer

A. 3 mg/kg/dose twice daily for 3 months
The recommended dose is 3–6 mg/kg/day for 2–3 months; 3 mg/kg/dose twice daily is equal to 6 mg/kg/day. Dividing the total daily dose will decrease gastrointestinal side effects.

Which of the following strategies would be most effective when providing diet instruction to Catalina?
  1. a.
    Ask her to identify her food likes and dislikes.
  2. b.
    List the foods she must eat each week.
  3. c.
    Explain that she needs to make these changes on just a short-term basis until her anemia resolves.
  4. d.
    Explain that the iron supplement has side effects that she will have to tolerate if she is prescribed that medication.

Answer

A. Ask her to identify her food likes and dislikes.
Having the client identify their food likes and dislikes is a collaborative strategy the nurse can use to develop a diet plan. Adolescents are more likely to adhere to diet modifications if they are partners in developing their nutritional plan.

Case Study 10.3.3 §10.3 source ↗

Read the following clinical scenario and then answer the questions that follow. This case study is a follow-up to Case Study Part A.

Catalina’s health care provider confirms that her physical exam is normal other than signs of pallor. A complete blood count (CBC) and ferritin level are ordered to evaluate for ID and anemia. Catalina is also referred to a gynecologist for further evaluation of her heavy menstrual bleeding.

Catalina’s laboratory test results reveal a hemoglobin level of 7 g/dL (expected range: 12–15 g/dL) and a ferritin level of 9 ng/mL (expected range: 12–150 ng/mL), confirming IDA. She is started on oral iron replacement and counseled on foods to avoid while taking oral iron for better absorption. She is also encouraged to add iron-rich foods to her diet daily and to return in 6 weeks.

At her 6-week follow-up visit, Catalina reports that she is feeling less tired, and her shortness of breath has resolved. Her hemoglobin level at this visit is 10 g/dL. She has also been evaluated by a gynecologist and started on oral birth control pills to decrease her heavy menstrual bleeding. Catalina is instructed to continue oral iron therapy for at least 2 more months and then return for follow-up.

The nurse should include which of the following in Catalina’s discharge instructions regarding taking oral iron?
  1. a.
    Iron should be taken with milk or tea.
  2. b.
    If stomach discomfort occurs, take the iron with an antacid.
  3. c.
    If a dose is missed, double the dose for the next day.
  4. d.
    Iron should be taken with orange juice to enhance absorption.

Answer

D. Iron should be taken with orange juice to enhance absorption.
Taking iron with orange juice will increase gastrointestinal absorption. Taking iron with milk, tea, or coffee can decrease its absorption. Antacids should be taken 2 hours before or 4 hours after taking iron for better absorption because iron is better absorbed in an acidic environment. Missed doses of iron should not be made up.

Case Study 10.3.4 §10.3 source ↗

Read the following clinical scenario and then answer the questions that follow. This case study is a follow-up to Case Study Part A.

  4. d.
    Increased menstrual bleeding

Answer

C. Weakness and dizziness
Feeling weak and dizzy may be a sign of low hemoglobin or worsening anemia. This can occur if oral iron is not absorbed sufficiently by the body.
