1. An older adult patient comes to the clinic complaining of not being able to do what he used to be able to. You know that normal changes associated with aging include:

A. Improved blood flow
B. Slowed metabolic rate
C. Increased brain weight
D. Improved nerve fiber conduction

Correct answer: B

Rationale: Normal changes associated with aging include a slowed metabolic rate and decreased brain weight. Option A, 'Improved blood flow,' is incorrect as aging is generally associated with reduced vascular health rather than improved blood flow. Option D, 'Improved nerve fiber conduction,' is incorrect as aging typically leads to a decline in nerve function rather than improvement.

2. Anemia of chronic inflammation is generally classified as:

A. Hypochromic and microcytic.
B. Hypochromic and macrocytic.
C. Normochromic and microcytic.
D. Normochromic and normocytic.

Correct answer: D

Rationale: Anemia of chronic inflammation is typically characterized by normochromic (normal hemoglobin content) and normocytic (normal cell size) red blood cells. Choice A, hypochromic and microcytic, is incorrect because hypochromic refers to reduced hemoglobin content and microcytic refers to smaller than normal red blood cells, which are not typically seen in anemia of chronic inflammation. Choice B, hypochromic and macrocytic, is also incorrect as macrocytic refers to larger than normal red blood cells. Choice C, normochromic and microcytic, is incorrect because microcytic red blood cells are smaller than normal. Therefore, the correct classification for anemia of chronic inflammation is normochromic and normocytic.

3. A hemoglobin electrophoresis is done to evaluate for sickle cell disease. The report reveals the person has HbAS, which means the person:

A. is normal with no sickle cell disease.
B. is a sickle cell carrier.
C. has sickle cell anemia.
D. has thalassemia.

Correct answer: B

Rationale: HbAS indicates sickle cell trait, not full-blown sickle cell anemia. Choice A is incorrect because HbAS indicates the presence of the sickle cell trait. Choice C is incorrect as sickle cell anemia is characterized by HbSS, not HbAS. Choice D is incorrect as thalassemia is a different type of hemoglobin disorder not indicated by HbAS.

4. A patient was sneezing frequently after a few days of allergic rhinitis, and she noticed her eye became red. She denies any trauma, eye pain, or visual disturbance. Physical examination reveals a subconjunctival hemorrhage. Which statement is accurate pertaining to this case?

A. The hemorrhage will resolve without treatment within 2 weeks.
B. The patient should be referred for immediate ophthalmologic examination.
C. Corticosteroid eye drops will be prescribed to reduce the bleeding.
D. Antibiotic eye drops will be prescribed to prevent infection.

Correct answer: A

Rationale: The correct answer is A: 'The hemorrhage will resolve without treatment within 2 weeks.' Subconjunctival hemorrhage typically resolves on its own without treatment. It is a self-limiting condition that does not require specific intervention. Choice B is incorrect as immediate ophthalmologic examination is not necessary for subconjunctival hemorrhage unless there are other concerning symptoms or risk factors present. Choice C is incorrect because corticosteroid eye drops are not typically used for subconjunctival hemorrhage. Choice D is also incorrect as antibiotic eye drops are not indicated since subconjunctival hemorrhage is not due to an infection.

5. Seizures are diagnosed by which of the following?

A. Electroencephalogram (EEG) and ECG
B. Seizure symptoms and complete blood count (CBC)
C. Seizure symptoms and electrocardiogram (ECG)
D. Seizure symptoms and EEG

Correct answer: D

Rationale: Seizures are most accurately diagnosed by EEG, which measures brain activity. Choice A is incorrect as ECG (electrocardiogram) measures heart activity, not brain activity. Choice B is incorrect as CBC (complete blood count) is a blood test and not used to diagnose seizures. Choice C is incorrect as an ECG (electrocardiogram) also measures heart activity, not brain activity, and is not the primary diagnostic tool for seizures.
