1. Which type of cells secrete insulin?

• A. alpha cells
• B. beta cells
• C. CD4 cells
• D. helper cells

Correct answer: B

Rationale: Beta cells are responsible for secreting insulin. Insulin is produced by beta cells in the pancreas and plays a crucial role in regulating blood sugar levels. Alpha cells secrete glucagon, not insulin (Choice A). CD4 cells are a type of immune cell that helps coordinate the immune response (Choice C). Helper cells are a type of immune cell that aids in activating other immune cells (Choice D). Therefore, the correct answer is beta cells.

2. A healthcare provider is caring for a patient who has experienced burns to the right lower extremity. According to the Rule of Nines, which of the following percentages most accurately describes the severity of the injury?

• A. 36%
• B. 27%
• C. 18%
• D. 9%

Correct answer: C

Rationale: According to the Rule of Nines, the right lower extremity accounts for 18% of the total body surface area. The Rule of Nines divides the body into regions, each representing 9% or a multiple of 9%, allowing for a quick estimation of the extent of burns. In this case, the correct answer is 18% as it corresponds to the percentage allocated for each lower extremity. Choices A, B, and D are incorrect as they do not match the standard allocation for the right lower extremity in the Rule of Nines.

3. When a person using over-the-counter nasal decongestant drops experiences unrelieved and worsening nasal congestion, what should be instructed?

• A. switch to a stronger dose of the same medication.
• B. discontinue the medication for a few weeks.
• C. continue taking the same medication, but use it more frequently.
• D. use a combination of medications for better relief.

Correct answer: B

Rationale: When a person using over-the-counter nasal decongestant drops experiences unrelieved and worsening nasal congestion, it is crucial to discontinue the medication for a few weeks. Prolonged use of decongestant drops can lead to rebound congestion, which is relieved by stopping the medication for a period of time. Nasal congestion occurs due to various factors like infection, inflammation, or allergy, leading to swelling of the nasal cavity. Nasal decongestants work by stimulating alpha-adrenergic receptors, causing vasoconstriction and shrinking of nasal mucous membranes. However, prolonged use can result in vasodilation, worsening nasal congestion. Switching to a stronger dose of the same medication is not recommended as it can exacerbate the issue. Continuing the same medication more frequently or using a combination of medications are also not advised and may lead to side effects. Educating individuals on proper decongestant use and potential risks of prolonged usage is essential, especially for those with specific health conditions.

4. What is pica?

• A. dependency on alcohol
• B. increased iron in the diet
• C. the sickle cell trait
• D. eating ice

Correct answer: D

Rationale: Pica is a disorder characterized by the ingestion of nonfood substances, which can lead to a clinical iron deficiency. It may be the first sign of an underlying issue. Individuals with pica consume a variety of nonfood items such as ice, clay, dirt, or paste. Choice A, dependency on alcohol, is incorrect as it is not related to pica. Choice B, increased iron in the diet, is incorrect because pica involves ingesting nonfood items rather than having an increased intake of iron. Choice C, the sickle cell trait, is unrelated to pica and is therefore incorrect.

5. A nurse is instructing a patient about the warning signs of Digitalis side effects. Which of the following side effects should the nurse tell the patient are sometimes associated with excessive levels of Digitalis?

• A. Seizures
• B. Muscle weakness
• C. Depression
• D. Anxiety

Correct answer: B

Rationale: The correct answer is 'Muscle weakness.' Palpitations and muscle weakness are commonly associated with excessive levels of Digitalis. Seizures, depression, and anxiety are not typically linked to Digitalis toxicity. Seizures could be more related to other medications or conditions, while depression and anxiety are not commonly reported side effects of Digitalis.
