Nokea
A patient presents with a painful, vesicular rash following a linear pattern on the left forearm. The patient reports a history of gardening without gloves. Which of the following conditions is most likely responsible for this presentation?
- A. Allergic contact dermatitis
- B. Herpes simplex virus infection
- C. Scabies
- D. Poison ivy dermatitis
Correct Answer: B
Rationale: The correct answer is B: Herpes simplex virus infection. The presentation of a painful, vesicular rash following a linear pattern on the left forearm is characteristic of herpes simplex virus infection, specifically herpes zoster (shingles). The linear pattern is due to the virus following a specific nerve pathway. This is different from the other choices - A: Allergic contact dermatitis typically presents as a diffuse rash at the site of contact with an allergen, not a linear pattern. C: Scabies presents with burrows and papules, not vesicles in a linear pattern. D: Poison ivy dermatitis causes a diffuse rash, not a linear vesicular rash.

A common chronic complication of diabetes due to the thickening of the capillaries and arterioles of the eye is?
- A. Papilledema
- B. Glaucoma
- C. Retinal Detachment
- D. Diabetic retinopathy
Correct Answer: D
Rationale: The correct answer is D: Diabetic retinopathy. This condition is a common complication of diabetes that occurs due to the thickening of capillaries and arterioles in the eye, leading to damage to the retina. This can result in vision problems and even blindness if left untreated.
A: Papilledema is the swelling of the optic disc due to increased intracranial pressure, not related to diabetes.
B: Glaucoma is a condition characterized by increased pressure within the eye, not directly caused by diabetes.
C: Retinal detachment is the separation of the retina from the underlying tissues, which is not primarily caused by diabetes-related capillary changes.
A patient presents with severe sore throat, fever, and enlarged tonsils with exudate. Rapid antigen testing confirms group A beta-hemolytic Streptococcus (GAS) infection. Which of the following medications is the first-line treatment for this condition?
- A. Amoxicillin
- B. Azithromycin
- C. Cephalexin
- D. Clindamycin
Correct Answer: A
Rationale: The correct answer is A: Amoxicillin. Amoxicillin is the first-line treatment for GAS pharyngitis due to its effectiveness against Streptococcus bacteria. It is a penicillin-class antibiotic recommended by guidelines. Azithromycin is an alternative for patients allergic to penicillin. Cephalexin is not the first-line choice for GAS. Clindamycin is reserved for patients allergic to both penicillin and macrolides.
Which of the following conditions is characterized by inflammation of the plantar fascia, resulting in heel pain that is typically worse with the first steps in the morning?
- A. Achilles tendinitis
- B. Plantar fasciitis
- C. Morton's neuroma
- D. Stress fracture of the calcaneus
Correct Answer: B
Rationale: Plantar fasciitis is the correct answer. It is characterized by inflammation of the plantar fascia, leading to heel pain, especially in the morning. The plantar fascia is a band of tissue that connects the heel bone to the toes. The pain is usually worse with the first steps after resting.
Achilles tendinitis involves inflammation of the Achilles tendon, which connects the calf muscles to the heel bone, causing pain at the back of the heel and ankle. Morton's neuroma is a condition involving a thickening of tissue around a nerve in the ball of the foot, leading to sharp, burning pain in the toes.
Stress fracture of the calcaneus refers to a small crack in the heel bone due to repetitive stress or overuse, resulting in heel pain that may worsen with activity, but not specifically with the first steps in the morning.
A patient presents with recurrent episodes of brief, severe, stabbing pain in the distribution of the trigeminal nerve. Episodes are triggered by touch, chewing, or cold exposure. Which of the following neurological conditions is most likely responsible for these symptoms?
- A. Migraine headache
- B. Cluster headache
- C. Tension-type headache
- D. Trigeminal neuralgia
Correct Answer: D
Rationale: The correct answer is D: Trigeminal neuralgia. This condition is characterized by recurrent, severe, stabbing pain in the trigeminal nerve distribution triggered by touch, chewing, or cold exposure. The key feature is the characteristic lancinating pain, which is not typical of migraine (choice A), cluster headache (choice B), or tension-type headache (choice C). Migraine typically presents with pulsating, moderate to severe headache associated with nausea and sensitivity to light and sound. Cluster headache is characterized by severe, unilateral pain around the eye associated with autonomic symptoms. Tension-type headache presents with bilateral, pressing or tightening pain without specific triggers. Therefore, based on the description of the symptoms in the question, trigeminal neuralgia is the most likely diagnosis.
To promote drainage and reduce pressure from fluid, Nurse Selma nursing intervention is to have the child assume any of the following positions, EXCEPT _____.
- A. tilt head to side if sitting up.
- B. Lie on the affected area
- C. put the pillows behind the head
- D. lie on the non-affected ear.
Correct Answer: B
Rationale: The correct answer is B: Lie on the affected area. This position would hinder drainage and increase pressure on the affected area. A: Tilt head to the side if sitting up, is correct as it promotes drainage. C: Putting pillows behind the head can also aid drainage. D: Lying on the non-affected ear can help reduce pressure on the affected side.
