What is the role of a nurse during scratch test to detect allergies?
- A. Applying the liquid test antigen
- B. Determining the type of allergy
- C. Measuring the length and width of the
- D. Documenting the findings raised wheal
Correct Answer: A
Rationale: During a scratch test to detect allergies, one of the key roles of a nurse is to apply the liquid test antigen onto the patient's skin. The liquid test antigen contains small amounts of common allergens that could trigger a reaction in individuals who are allergic to them. By applying the test antigen onto the skin and creating small scratches or pricks, the nurse can observe if the patient develops a raised, red, itchy bump called a wheal at the site of the allergen exposure. This helps in identifying specific allergies and determining the appropriate treatment plan for the patient.

On the third day after a partial thyroidectomy, a client exhibits muscle twitching and hyperirritability of the nervous system. When questioned, the client reports numbness and tingling of the mouth and fingertips. Suspecting a life- threatening electrolyte disturbance, the nurse notifies the surgeon immediately. Which electrolyte disturbance most commonly follows thyroid surgery?
- A. Hypocalcemia
- B. Hyperkalemia
- C. Hyponatremia
- D. Hypermagnesemia
Correct Answer: A
Rationale: Hypocalcemia is the most common electrolyte disturbance that follows thyroid surgery, particularly after a partial thyroidectomy. This occurs due to inadvertent injury or removal of the parathyroid glands, which are responsible for regulating calcium levels in the body. The symptoms of hypocalcemia, such as muscle twitching, hyperirritability of the nervous system, numbness, and tingling, align with the client's presentation in this scenario. Prompt recognition and treatment of hypocalcemia are crucial to prevent life-threatening complications like tetany or seizures. Therefore, the nurse's decision to notify the surgeon immediately is appropriate to address this electrolyte imbalance.
The nurse is explaining the action of insulin to a newly diagnosed diabetic client. During the teaching, the nurse reviews the process of insulin secretion in the body. The nurse is correct when stating that insulin is secreted from the:
- A. adenohypohysis.
- B. alpha cells of the pancreas.
- C. beta cells of the pancreas.
- D. parafollicular cells of the thyroid.
Correct Answer: C
Rationale: Insulin is secreted from the beta cells of the pancreas. These specialized cells are located in the islets of Langerhans within the pancreas. When blood glucose levels rise after eating, beta cells release insulin into the bloodstream to help regulate glucose levels by allowing cells to take in glucose for energy or storage. Insulin also helps lower blood sugar by promoting the conversion of glucose to glycogen in the liver and muscles. Therefore, the nurse is correct in stating that insulin is secreted from the beta cells of the pancreas.
Which of the ff is a sign or symptom characteristic of the later stages of TB?
- A. Fatigue
- B. Anorexia
- C. Hemoptysis
- D. Weight loss
Correct Answer: C
Rationale: Hemoptysis, which refers to coughing up blood, is a sign characteristic of the later stages of tuberculosis (TB). This symptom occurs when there is significant damage to the lungs due to the progression of the disease. Hemoptysis in TB can indicate advanced disease and the presence of cavities in the lungs where blood vessels may become eroded. It is a serious symptom that often requires immediate medical attention. While fatigue, anorexia, and weight loss are common symptoms of TB, hemoptysis specifically points towards the later stages of the disease and severe lung involvement.
The nurse is taking care of a 2-year-old child with a macule skin lesion. Which clinical finding should the nurse expect to assess with this type of lesion?
- A. Flat, nonpalpable, and irregularly shaped lesion that is greater than 1 cm in diameter
- B. Heaped-up keratinized cells, flaky exfoliation, irregular, thick or thin, dry or oily, varied in size
- C. Flat, brown mole less than 1 cm in diameter
- D. Elevated, flat-topped, firm, rough, superficial papule greater than 1 cm in diameter
Correct Answer: A
Rationale: A macule is a flat, nonpalpable, and discolored area on the skin that is less than 1 cm in diameter. This type of skin lesion is typically characterized by a change in color without any change in texture or thickness of the skin. The clinical finding associated with a macule is a flat, nonpalpable lesion that is smaller in size (less than 1 cm) and regularly shaped. Therefore, the nurse should expect to assess a flat, nonpalpable, and irregularly shaped lesion that is greater than 1 cm in diameter with a different type of skin lesion, not a macule.
Sudden infant death syndrome (SIDS) is one of the most common causes of death in infants. At what age is the diagnosis of SIDS most likely?
- A. At 1 to 2 years of age
- B. At I week to 1 year of age, peaking at 2 to 4 months
- C. At 6 months to 1 year of age, peaking at 10 months
- D. At 6 to 8 weeks of age
Correct Answer: B
Rationale: Sudden infant death syndrome (SIDS) is most likely to occur between the ages of 1 week to 1 year, with the highest risk period being between 2 to 4 months of age. While SIDS can occur up to the age of 1 year, the peak incidence is during the first 6 months of life. It is important to follow safe sleep practices, such as placing infants on their backs to sleep, to reduce the risk of SIDS during this vulnerable period.
