1. A 10-year-old male presents to his primary care provider reporting wheezing and difficulty breathing. History reveals that both of the child's parents suffer from allergies. Which of the following terms would be used to classify the child?

Correct answer: B

Rationale: In this case, the correct term to classify the child is 'Atopic.' Atopic individuals have a genetic predisposition to developing allergic conditions, as seen in this patient with a family history of allergies. 'Desensitized' refers to reduced sensitivity to an allergen, which is not the case here. 'Hyperactive' relates to an exaggerated response, and 'Autoimmune' involves the immune system attacking its own cells, neither of which accurately describes the child's classification based on the provided history.

2. A 58-year-old woman comes to the clinic for evaluation of a sharp, intermittent, severe, stabbing facial pain that she describes as 'like an electric shock.' The pain occurs only on one side of her face; it seems to be triggered when she chews, brushes her teeth, or sometimes when she merely touches her face. There is no numbness associated with the pain. What is most likely causing her pain?

Correct answer: B

Rationale: The correct answer is B: Trigeminal neuralgia. Trigeminal neuralgia is characterized by severe, stabbing pain in the distribution of the trigeminal nerve, often triggered by light touch, chewing, or brushing teeth. In this case, the patient's symptoms of sharp, intermittent facial pain triggered by activities like chewing and touching her face are classic for trigeminal neuralgia. Choices A, C, and D are incorrect. Temporal arteritis typically presents with unilateral headache, jaw claudication, and visual symptoms. Migraine headaches are usually throbbing in nature and often associated with nausea, vomiting, and sensitivity to light and sound. Cluster headaches are characterized by severe unilateral pain around the eye with autonomic symptoms like lacrimation and nasal congestion.

3. After studying about fungi, which information indicates a correct understanding of fungi? Fungi causing deep or systemic infections:

Correct answer: D

Rationale: The correct answer is D: 'Are commonly opportunistic.' Fungi causing deep or systemic infections are commonly opportunistic, particularly in individuals with compromised immune systems. Choice A is incorrect because fungi infections are not easily treated with penicillin. Choice B is incorrect as deep or systemic fungal infections are not extremely rare. Choice C is incorrect as fungal infections can co-occur with other infections.

4. When educating a client about to undergo a pacemaker insertion, the nurse explains the normal phases of cardiac muscle tissue. During the repolarization phase, the nurse will stress that membranes must be repolarized before they can be re-excited. Within the cell, the nurse understands that:

Correct answer: A

Rationale: During the repolarization phase of cardiac muscle tissue, potassium channels open while sodium channels close. This process is crucial for the cardiac muscle to return to its resting state after depolarization. Potassium moving out of the cell and sodium staying out helps reset the membrane potential and prepare the cell for the next depolarization phase. The influx of calcium is not the primary stimulus for repolarization in cardiac tissue; it is mainly involved in the depolarization phase. While electrical activity within the heart influences repolarization, the specific ion movements described in choice A are what physiologically drive repolarization. Cell membranes need to be in an active state during repolarization, not calm, to facilitate the necessary ion movements for muscle tissue to properly function.

5. What condition can be caused by an excessive amount of growth hormone released by the pituitary gland in childhood?

Correct answer: B

Rationale: Gigantism is the correct answer. It is a condition caused by excessive growth hormone release before the epiphyseal plates close, leading to abnormal growth. Acromegaly (choice A) is caused by excess growth hormone after the epiphyseal plates close, resulting in enlargement of bones and tissues. Syndrome of inappropriate antidiuretic hormone (choice C) is characterized by the excessive release of antidiuretic hormone, leading to water retention and dilutional hyponatremia. Dwarfism (choice D) is a condition characterized by significantly below-average height.
