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: IgG
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’s chart indicates a history of ketoacidosis. Which of the following would you not expect to see with this patient if this condition were acute?
- A. Vomiting
- B. Extreme Thirst
- C. Weight gain
- D. Acetone breath smell
Correct answer: Weight gain
Rationale: In acute ketoacidosis, a patient typically experiences rapid weight loss due to the body burning fat and muscle for energy in the absence of sufficient insulin. Therefore, weight gain would not be expected. Vomiting may occur due to the metabolic disturbances associated with ketoacidosis. Extreme thirst is a common symptom as the body tries to compensate for dehydration. Acetone breath smell is a classic sign of ketoacidosis as acetone is one of the ketones produced during this condition.
3. Clinical manifestations of asthma include:
- A. Decreased expiratory time
- B. Increased peak expiratory flow
- C. Increased use of accessory muscles
- D. Increased oxygen saturation
Correct answer: Increased use of accessory muscles
Rationale: Clinical manifestations of asthma include increased use of accessory muscles, increased expiratory time, increased peak expiratory flow, and decreased oxygen saturation. Choice A, 'Decreased expiratory time,' is incorrect because asthma typically presents with increased expiratory time due to airway obstruction. Choice B, 'Increased peak expiratory flow,' is incorrect as asthma commonly leads to decreased peak expiratory flow due to airway constriction. Choice D, 'Increased oxygen saturation,' is incorrect because asthma exacerbations often result in decreased oxygen saturation levels.
4. The nurse is assessing an infant with developmental dysplasia of the hip. Which finding would the nurse anticipate?
- A. Unequal leg length
- B. Limited adduction
- C. Diminished femoral pulses
- D. Symmetrical gluteal folds
Correct answer: Unequal leg length
Rationale: In developmental dysplasia of the hip (DDH), one of the key findings is unequal leg length. This occurs due to the dislocation of the hip joint, where the ball is loose in the socket. Limited adduction, the inability to bring the hip and knee towards the midline of the body, is also a common finding in DDH. Diminished femoral pulses are not typically associated with DDH, as it primarily affects the skeletal structure rather than vascular supply. Symmetrical gluteal folds are normal in infants and do not indicate DDH, as asymmetry in gluteal folds can be a sign of hip dislocation.
5. The nurse is caring for a client in the late stages of Amyotrophic Lateral Sclerosis (A.L.S.). Which finding would the nurse expect?
- A. Confusion
- B. Loss of half of the visual field
- C. Shallow respirations
- D. Tonic-clonic seizures
Correct answer: Shallow respirations
Rationale: In the late stages of Amyotrophic Lateral Sclerosis (A.L.S.), respiratory muscles are affected, leading to shallow respirations. Confusion is not typically associated with A.L.S. Loss of half of the visual field suggests a neurological issue unrelated to A.L.S., while tonic-clonic seizures are not commonly seen in A.L.S. patients. Shallow respirations are a hallmark sign of respiratory muscle weakness in A.L.S. due to the degeneration of motor neurons.
