1. Macular degeneration occurs as a result of:

• A. loss of lens accommodation
• B. detachment of the retina
• C. increased intraocular pressure
• D. impaired blood supply leading to cellular waste accumulation and ischemia

Correct answer: D

Rationale: Macular degeneration is a condition that affects the macula, a part of the retina responsible for central vision. It is primarily caused by impaired blood supply to the macula, leading to cellular waste accumulation and ischemia. This results in the death of photoreceptor cells and ultimately vision loss. Choices A, B, and C are incorrect because macular degeneration is not related to the loss of lens accommodation, detachment of the retina, or increased intraocular pressure. The correct answer directly addresses the underlying pathophysiology of macular degeneration.

2. Which of the following outcome criteria is appropriate for a client with dementia?

• A. The client will return to an established schedule for activities of daily living.
• B. The client will learn new coping mechanisms to handle anxiety.
• C. The client will seek out resources in the community for support.
• D. The client will follow an established schedule for activities of daily living.

Correct answer: D

Rationale: The correct answer is D. For clients with dementia, following an established schedule for activities of daily living is appropriate as it helps maintain routine and structure, which can be beneficial for their condition. Choice A has been rephrased to align better with the context of dementia care. Choice A is incorrect as expecting a return to a previous level of self-functioning may not be realistic for clients with dementia. Choice B is not the most appropriate outcome criteria as handling anxiety, while important, may not be the primary focus when working with clients with dementia. Choice C, seeking out resources in the community for support, is also important but may not be as directly related to the day-to-day care and management of activities for a client with dementia.

3. Which immunoglobulin presents the first challenge to the antigen?

• A. IgA
• B. IgG
• C. IgM
• D. IgE

Correct answer: C

Rationale: IgM is the first immunoglobulin to challenge the antigen during an immune response. IgM is the primary antibody produced during the initial or primary immune response. It is efficient in agglutination and complement activation, making it crucial in the early stages of defense. IgA is mainly found in mucosal areas and secretions. IgG is the most abundant antibody in circulation and is involved in secondary immune responses. IgE is primarily associated with allergic reactions and parasitic infections. Therefore, IgM is the correct choice as it acts first during the immune response, while the other immunoglobulins have different roles and functions.

4. A patient's current medical condition is suggestive of impaired erythropoiesis. Which of the following laboratory studies would be most clinically relevant in diagnosing this health problem?

• A. White blood cell count with differential
• B. RBC, hemoglobin, and hematocrit
• C. INR and aPTT
• D. d-dimer and C-reactive protein

Correct answer: B

Rationale: In this scenario, where impaired erythropoiesis is suspected, the most clinically relevant laboratory studies would focus on red blood cell parameters. Therefore, assessing RBC count, hemoglobin levels, and hematocrit values would provide direct insights into erythropoiesis. Choices A, C, and D are not directly related to erythropoiesis assessment. White blood cell count with a differential is more indicative of immune response and infection. INR and aPTT are coagulation studies, while d-dimer and C-reactive protein levels are more associated with inflammation and thrombotic events.

5. A patient taking an oral contraceptive missed one pill. What should the nurse teach the patient to do?

• A. Take two pills as soon as you remember, then continue the regular schedule.
• B. Take one pill as soon as you remember, then continue the regular schedule.
• C. Skip the missed pill and continue the regular schedule.
• D. Take two pills immediately, then continue the regular schedule.

Correct answer: A

Rationale: When a patient taking an oral contraceptive misses one pill, the correct action is to take two pills as soon as they remember and then continue the regular schedule. Option A is the correct answer because doubling up the dose helps maintain the effectiveness of the contraceptive. Option B is incorrect because taking only one pill after missing one may decrease contraceptive effectiveness. Option C is wrong as skipping the missed pill can also reduce effectiveness. Option D is inaccurate because taking two pills immediately is not necessary; the patient should take the missed pill as soon as remembered and then resume the regular dosing schedule.
