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 3-year-old had a hip spica cast applied 2 hours ago. In order to facilitate drying, the nurse should
- A. Expose the cast to air and turn the child frequently
- B. Use a heat lamp to reduce the drying time
- C. Handle the cast with the abductor bar
- D. Turn the child as little as possible
Correct answer: A
Rationale: After applying a hip spica cast, it is important to facilitate drying by exposing the cast to air and turning the child frequently. This helps promote even drying and prevents complications such as skin breakdown. Using a heat lamp can cause burns and is not recommended. Handling the cast with the abductor bar does not aid in drying the cast. Turning the child as little as possible is incorrect as regular turning is crucial to prevent complications.
3. Why should a 30-year-old Caucasian woman who works the night shift take Vitamin D supplements?
- A. It's a standard part of the overall nutritional treatment for the prevention of osteomalacia.
- B. It helps your intestines absorb calcium, which is important for bone formation.
- C. It stimulates skin cells to produce calcium, which is then released into the bloodstream to be used for bone formation.
- D. Vitamin D supplements should not be taken by someone of your age.
Correct answer: B
Rationale: The correct answer is B: 'It helps your intestines absorb calcium, which is important for bone formation.' Vitamin D plays a crucial role in aiding the absorption of calcium from the intestines into the bloodstream, which is essential for bone health and formation. Choice A is incorrect because it does not specifically address the role of Vitamin D in calcium absorption. Choice C is incorrect as Vitamin D does not stimulate skin cells to produce calcium; rather, it helps regulate calcium levels in the body. Choice D is incorrect as age alone is not a contraindication for Vitamin D supplementation; the need for supplementation is based on individual health status and risk factors.
4. A nurse has just started her rounds delivering medication. A new patient on her rounds is a 4-year-old boy who is non-verbal. This child does not have any identification on. What should the nurse do?
- A. Contact the provider
- B. Ask the child to write their name on paper
- C. Ask a coworker about the identification of the child
- D. Ask the father who is in the room the child's name
Correct answer: D
Rationale: When encountering a non-verbal child without identification, it is appropriate for the nurse to ask the accompanying parent or guardian for the child's name. The father, being present in the room, can provide the necessary information. This ensures accurate identification to deliver the correct medication. Contacting the provider may cause unnecessary delays. Asking a non-verbal child to write their name is not feasible. Asking a coworker may not provide reliable identification as they may not have direct knowledge.
5. The healthcare provider is reviewing the lab results of a patient who has presented in the Emergency Room. The lab results show that the troponin T value is at 5.3 ng/mL. Which of these interventions, if not already completed, would take priority over the others?
- A. Place the patient in a 90-degree position
- B. Assess whether the patient is taking diuretics
- C. Obtain and attach defibrillator leads
- D. Assess the patient's last ejection fraction
Correct answer: C
Rationale: In this scenario, the elevated Troponin T level indicates cardiac damage, possibly due to a myocardial infarction. A Troponin T value of 5.3 ng/mL is significantly elevated (normal levels are below 0.2 ng/mL), suggesting acute cardiac injury. Given the setting of an Emergency Room and the critical nature of the situation, the priority intervention should be to obtain and attach defibrillator leads. Elevated Troponin T levels can indicate a higher risk of arrhythmias, including ventricular fibrillation, which can lead to sudden cardiac arrest. Defibrillator leads are essential for monitoring the patient's cardiac rhythm and readiness for immediate defibrillation if necessary. Placing the patient in a 90-degree position (Choice A) or assessing diuretic use (Choice B) are not immediate priorities in this critical situation. Additionally, assessing the patient's last ejection fraction (Choice D) is important but not as urgent as preparing for potential life-threatening arrhythmias requiring defibrillation.
