Nursing Elites

1. A 5-month-old child is admitted to the hospital with recurring respiratory infections. A possible cause of this condition is:

• A. Hypergammaglobulinemia
• B. Increased maternal IgG
• C. Immune insufficiency
• D. Decreased maternal antibody breakdown, resulting in hyposensitivity

Correct answer: C

Rationale: Immune insufficiency is a possible cause of recurring respiratory infections in a 5-month-old child. In this scenario, the child's immune system may not be functioning optimally, leading to a susceptibility to infections. Choices A, B, and D are incorrect. Hypergammaglobulinemia refers to high levels of gamma globulins in the blood and is not typically associated with recurring respiratory infections in this context. Increased maternal IgG would provide passive immunity to the child, offering some protection against infections. Decreased maternal antibody breakdown leading to hyposensitivity is not a common cause of recurring respiratory infections in a 5-month-old child.

2. A patient is starting on atorvastatin (Lipitor) for hyperlipidemia. What critical instruction should the nurse provide?

• A. Take the medication at night to reduce the risk of muscle pain and other side effects.
• B. Avoid consuming grapefruit juice while taking this medication.
• C. Take the medication in the morning with breakfast to improve absorption.
• D. Take the medication with a high-fat meal to increase its effectiveness.

Correct answer: A

Rationale: The correct answer is to take the medication at night to reduce the risk of muscle pain and other side effects. Atorvastatin, like other statins, is more effective when taken in the evening as the body produces more cholesterol at night. Taking it with a high-fat meal (choice D) is not recommended as it may reduce the drug's absorption. Grapefruit juice (choice B) should be avoided with atorvastatin as it can increase the risk of side effects. Taking the medication in the morning with breakfast (choice C) is not as effective as taking it at night.

3. Medroxyprogesterone acetate (Provera) is indicated for the treatment of women with

• A. uterine bleeding.
• B. cervical cancer.
• C. ovarian cancer.
• D. fibromyalgia.

Correct answer: A

Rationale: Medroxyprogesterone acetate (Provera) is commonly used to treat conditions like abnormal uterine bleeding, amenorrhea, and endometriosis. It helps regulate the menstrual cycle and reduce excessive bleeding. Therefore, the correct answer is A. Choice B, cervical cancer, is incorrect because Provera is not indicated for the treatment of cancer. Choice C, ovarian cancer, is also incorrect as Provera is not a primary treatment for ovarian cancer. Choice D, fibromyalgia, is unrelated to the use of medroxyprogesterone acetate.

4. The nurse is preparing to administer a vaccine to a newborn. Before administering the vaccine, the nurse should

• A. warm the vaccine to room temperature.
• B. gently cleanse the chosen injection site.
• C. check the infant's temperature.
• D. administer the full dose at a single injection site.

Correct answer: C

Rationale: Before administering a vaccine to a newborn, it is essential for the nurse to check the infant's temperature. This is important to ensure that the newborn does not have a fever, which could indicate an underlying infection or illness. Warming the vaccine to room temperature is not necessary and could be harmful. Vigorously massaging the injection site is not recommended as it can cause discomfort and tissue damage. Dividing the dose for administration to three injection sites is not standard practice for vaccine administration to a newborn.

5. A patient with an 18 pack per year history presents to a family practice clinic complaining of painless hoarseness and inability to clear mucus. A biopsy of respiratory tract cells is taken and shows that these cells have been replaced by less mature squamous epithelium cells. The nurse knows this type of change is referred to as:

• A. Dysplasia
• B. Metaplasia
• C. Hyperplasia
• D. Coagulation

Correct answer: B

Rationale: Metaplasia is the replacement of one type of cell with another, which can occur in response to chronic irritation, such as from smoking. In this case, the respiratory tract cells being replaced by less mature squamous epithelium cells indicate metaplasia. Dysplasia refers to abnormal development or growth of cells, not replacement; hyperplasia is an increase in the number of cells, not a replacement; and coagulation is a process related to blood clotting, not cell replacement.
