1. A patient is starting on oral contraceptives. What should the nurse emphasize about the importance of taking the medication at the same time each day?

A. Taking the medication at the same time each day helps maintain stable hormone levels and ensures effectiveness.
B. Taking the medication at the same time each day reduces the risk of breakthrough bleeding.
C. Taking the medication at the same time each day ensures consistent absorption and effectiveness.
D. Taking the medication at the same time each day is important, but missing a dose occasionally is not a concern.

Correct answer: A

Rationale: The correct answer is A. Taking oral contraceptives at the same time each day helps maintain stable hormone levels and ensures their effectiveness in preventing pregnancy. Choice B is incorrect because the primary emphasis of consistent timing is on hormone levels and effectiveness, not on reducing breakthrough bleeding. Choice C is incorrect because while consistent absorption is a factor, the main focus is on maintaining stable hormone levels. Choice D is incorrect as missing doses can significantly impact contraceptive efficacy.

2. Which of the following is an example of a Type 1 hypersensitivity reaction?

A. Anaphylaxis
B. Indigestion
C. Beta cell destruction
D. ABO transfusion reaction

Correct answer: A

Rationale: Anaphylaxis is a classic example of a Type 1 hypersensitivity reaction. In Type 1 hypersensitivity, allergens trigger an immediate immune response mediated by IgE antibodies, leading to the release of histamine and other mediators. This reaction can result in symptoms ranging from mild itching and hives to severe conditions like anaphylaxis, which is a life-threatening emergency. The other options, such as indigestion (choice B), beta cell destruction (choice C), and ABO transfusion reaction (choice D), are not classified as Type 1 hypersensitivity reactions. Indigestion is typically related to gastrointestinal disturbances, beta cell destruction is associated with autoimmune conditions like type 1 diabetes, and ABO transfusion reaction involves antibodies targeting incompatible blood groups, which is a different immune mechanism compared to Type 1 hypersensitivity.

3. Which type of lymphocyte recognizes and eliminates virus-infected cells and cancerous cells?

A. Neutrophils
B. Macrophages
C. Natural killer cells
D. Langerhans cells

Correct answer: C

Rationale: Natural killer cells are a type of lymphocyte that plays a crucial role in recognizing and eliminating virus-infected cells and cancerous cells. Neutrophils (Choice A) are a type of white blood cell involved in fighting infections, mainly through phagocytosis. Macrophages (Choice B) are another type of white blood cell that engulfs and digests cellular debris and pathogens. Langerhans cells (Choice D) are a type of dendritic cell found in the skin and mucosa, primarily involved in antigen presentation.

4. Which electrolyte imbalance does the nurse suspect in a patient with hyperaldosteronism?

A. Hyponatremia
B. Hypernatremia
C. Hyperkalemia
D. Hypercalcemia

Correct answer: C

Rationale: In a patient with hyperaldosteronism, the nurse would suspect hyperkalemia. Hyperaldosteronism leads to increased potassium excretion, resulting in low potassium levels in the blood. Therefore, choices A (Hyponatremia), B (Hypernatremia), and D (Hypercalcemia) are incorrect. Hyponatremia refers to low sodium levels, Hypernatremia refers to high sodium levels, and Hypercalcemia refers to high calcium levels, none of which are typically associated with hyperaldosteronism.

5. What is a potential implication of multiple dark bands on the nails?

A. They are considered a normal variant.
B. They can be associated with malignant melanoma.
C. They are indicative of a nail fungus.
D. They are associated with aging.

Correct answer: B

Rationale: Multiple dark bands on the nails can be a concerning sign of malignant melanoma, a type of skin cancer that can affect the nails. While some nail changes are considered normal variants, dark bands should not be dismissed lightly as they can indicate a serious condition like melanoma. Nail fungus typically presents differently, causing discoloration, thickening, or distortion of the nail without distinct dark bands. Additionally, aging can lead to various nail changes, but dark bands alone are not a common feature of normal aging.
