A patient presents with well-demarcated, hypopigmented macules with fine scaling, affecting the trunk and proximal extremities. The patient reports a history of sun exposure and outdoor activities. Which of the following conditions is most likely responsible for this presentation?

  • A. Tinea versicolor
  • B. Vitiligo
  • C. Pityriasis rosea
  • D. Seborrheic keratosis
Correct Answer: A

Rationale: The presentation of well-demarcated, hypopigmented macules with fine scaling on the trunk and proximal extremities is classic for tinea versicolor. Tinea versicolor is a common superficial fungal infection caused by Malassezia spp., which leads to hypo- or hyperpigmented patches on the skin. The condition often occurs in individuals with increased sebum production due to factors such as hot and humid climates, sweating, and oily skin. History of sun exposure and outdoor activities is also commonly reported by patients with tinea versicolor. Treatment usually involves antifungal medications applied topically or taken orally to eliminate the fungus. Differentiating tinea versicolor from other skin conditions, such as vitiligo, pityriasis rosea, or seborrheic keratosis, is important for appropriate management.

An EMT approaches an accident victim. The victim says, "Don't touch me!" The EMT says, you need help, but the victim replies NO! don't touch me. If the EMT takes the victim by the arm and forces the victim into the ambulance, the EMT could be guilty of:

  • A. Battery
  • B. Negligence
  • C. Malpractice
  • D. Assault
Correct Answer: A

Rationale: Battery refers to the intentional and offensive physical contact with another person without their consent, resulting in harm or injury. In this scenario, the victim clearly expressed their unwillingness to be touched or helped by saying, "Don't touch me!" multiple times. By ignoring the victim's refusal and physically forcing them into the ambulance, the EMT is committing battery even though they may have had good intentions to provide assistance. It is important for medical professionals, including EMTs, to always respect a person's right to refuse medical treatment or assistance, even in emergency situations.

Nurse Roberto is aware that a client who has experienced cardiac arrest is MOST at risk for which of the following imbalances?

  • A. Metabolic alkalosis
  • B. Metabolic acidosis
  • C. Respiratory alkalosis
  • D. Respiratory acidosis
Correct Answer: D

Rationale: When a client experiences cardiac arrest, their breathing may become insufficient, leading to inadequate elimination of carbon dioxide (CO2) from the body. With reduced CO2 elimination, the level of CO2 in the bloodstream increases, causing respiratory acidosis. This imbalance is characterized by a decrease in blood pH along with an increase in CO2 levels in the blood, resulting in an acidic environment. Respiratory acidosis is the most common imbalance seen in clients who have experienced cardiac arrest, as impaired gas exchange impacts the body's ability to maintain proper acid-base balance.

Based on the 2017 demography report (July 2016 estimate), the Philippine population has reached:

  • A. 140 million
  • B. 102 million
  • C. 120 million
  • D. 85 million
Correct Answer: B

Rationale: According to the 2017 demography report based on the July 2016 estimate, the Philippine population was approximately 102 million. This data is derived from official census data and estimates made by the Philippine Statistics Authority. As of that time, the country's population had not reached 140 million, 120 million, or 85 million as the other options suggest.

You accidentally touch Claudia's eyelid during eye drop instillation causing her to blink. What should have you done to prevent this from occurring?

  • A. Touch the inner side of the medicine cap
  • B. Tilt back Claudia's head slightly
  • C. Hold the dropper close to the eye but do not allow the medication to fall into the cornea
  • D. Have Claudia look up and focus on something
Correct Answer: B

Rationale: Tilt back Claudia's head slightly would have been the correct action to prevent her from blinking during eye drop instillation. By tilting her head back, you create a more stable position for instilling the eye drops, reducing the likelihood of accidental contact with her eyelid. Additionally, tilting the head back slightly helps in making it easier for the drops to enter the eye and stay within the conjunctival sac, improving the efficacy of the medication.

A patient presents with sudden-onset, painless vision loss in the right eye. Fundoscopic examination reveals a cherry-red spot at the macula and attenuated retinal vessels. Which of the following conditions is most likely responsible for this presentation?

  • A. Central retinal artery occlusion
  • B. Central retinal vein occlusion
  • C. Retinal detachment
  • D. Acute angle-closure glaucoma
Correct Answer: A

Rationale: The presentation of sudden-onset, painless vision loss in the right eye with a cherry-red spot at the macula and attenuated retinal vessels is classic for central retinal artery occlusion (CRAO). In this condition, the blockage of the central retinal artery results in severe ischemia of the retina, leading to rapid and profound vision loss. The cherry-red spot at the macula is a result of preserved choroidal circulation contrasting with the pale, ischemic retina. Attenuated retinal vessels are also commonly observed due to decreased blood flow. Prompt evaluation and management are critical in CRAO to potentially restore some vision and prevent further ischemic damage to the retina.
