1. A 34-year-old female has recently been diagnosed with an autoimmune disease. She has also recently discovered that she is pregnant. Which of the following is the only immunoglobulin that will provide protection to the fetus in the womb?
- A. IgA
- B. IgD
- C. IgE
- D. IgG
Correct answer: D
Rationale: IgG is the only immunoglobulin that can cross the placental barrier, providing passive immunity to the fetus. About 70-80% of the immunoglobulins in the blood are IgG. Specific IgG antibodies are generated after an initial exposure to an antigen, offering long-term protection against microorganisms. IgG antibodies are critical for protecting the fetus as they can be rapidly reproduced upon re-exposure to the same antigen. IgA is primarily found in mucosal areas, IgD is involved in antigen recognition, and IgE is associated with allergic reactions, but they do not provide the same level of protection to the fetus as IgG.
2. A patient with right lower-lobe pneumonia has been treated with IV antibiotics for 3 days. Which assessment data obtained by the nurse indicates that the treatment has been effective?
- A. Bronchial breath sounds are heard at the right base.
- B. The patient coughs up small amounts of green mucus.
- C. The patients white blood cell (WBC) count is 9000/L
- D. Increased tactile fremitus is palpable over the right chest
Correct answer: C
Rationale: The normal WBC count indicates that the antibiotics have been effective. All the other data suggest that a change in treatment is needed.
3. The healthcare professional calculates the IV flow rate for a patient receiving an antibiotic. The patient is to receive 100mL of the antibiotic over 30 minutes. The IV infusion set has a drop factor of 10 drops per milliliter. How many drops per minute should the healthcare professional set the IV to deliver?
- A. 11
- B. 19
- C. 26
- D. 33
Correct answer: D
Rationale: To determine the drops per minute for the IV flow rate, you can use the formula: Drops Per Minute = (Milliliters to be infused x Drop Factor) / Time in Minutes. Substituting the given values, you get 100 mL x 10 drops/mL / 30 minutes = 33 drops per minute. Therefore, the correct answer is 33, as the healthcare professional should set the IV to deliver 33 drops per minute to infuse the antibiotic correctly. Choices A, B, and C are incorrect as they do not match the calculated drops per minute based on the provided values.
4. A client has developed a vitamin C deficiency. Which of the following symptoms might the nurse most likely see with this condition?
- A. Cracks at the corners of the mouth
- B. Altered mental status
- C. Bleeding gums and loose teeth
- D. Anorexia and diarrhea
Correct answer: C
Rationale: A client with a severe vitamin C deficiency has a condition called scurvy. Scurvy is characterized by symptoms such as bleeding gums, loose teeth, poor wound healing, and easy bruising. The correct answer is 'Bleeding gums and loose teeth' because these are classic signs of scurvy due to vitamin C deficiency. Choice A ('Cracks at the corners of the mouth') is more indicative of a deficiency in B vitamins, specifically riboflavin. Choice B ('Altered mental status') is not typically associated with vitamin C deficiency but can occur with other conditions like vitamin B12 deficiency. Choice D ('Anorexia and diarrhea') are not common symptoms of vitamin C deficiency, as they are more commonly associated with other gastrointestinal issues or deficiencies in different nutrients.
5. Parents of a 6-month-old breastfed baby ask the nurse about increasing the baby's diet. Which of the following should be added first?
- A. Cereal
- B. Eggs
- C. Meat
- D. Juice
Correct answer: A
Rationale: The correct answer is 'Cereal.' The guidelines of the American Academy of Pediatrics recommend introducing one new food at a time, starting with strained cereal. Cereal is often recommended as a first solid food for infants due to its soft texture and iron-fortified properties, which are important for the baby's development. Eggs and meat are common allergenic foods and are usually introduced later. Juice is not recommended for infants under 1 year old due to its high sugar content and lack of nutritional value compared to whole fruits.
