Which type of drug could be used to treat asthma by opening airways wider?

  • A. sympatholytic drug
  • B. sympathomimetic drug
  • C. anticholinergic drug
  • D. parasympathomimetic drug
Correct Answer: B

Rationale: The correct answer is B: sympathomimetic drug. Sympathomimetic drugs stimulate the sympathetic nervous system, leading to bronchodilation and opening of airways wider, which is beneficial in treating asthma.
A: Sympatholytic drugs inhibit the sympathetic nervous system and would not be effective in widening airways in asthma treatment.
C: Anticholinergic drugs block the action of acetylcholine, which can cause bronchoconstriction and are not used to widen airways in asthma.
D: Parasympathomimetic drugs stimulate the parasympathetic nervous system, leading to bronchoconstriction and are not used to treat asthma by opening airways wider.

Considering the responsibilities and scope of practice for a nursing assistant, which of the following tasks is most appropriate for Nurse Edwards to delegate?

  • A. Checking for orthostatic changes in pulse and blood pressure.
  • B. Monitoring for improvement in tremor after levodopa (L-dopa) is given.
  • C. Adjusting the dosage of levodopa (L-dopa) based on the patient's response.
  • D. Monitoring for abnormal involuntary jerky movements of extremities.

A patient has a lesion involving the fasciculus gracilis and fasciculus cuneatus of the spinal cord. What should the nurse expect the patient to experience the loss of?

  • A. Pain and temperature sensations
  • B. Touch, deep pressure, vibration, and position sense
  • C. Subconscious information about body position and muscle tension
  • D. Voluntary muscle control from the cerebral cortex to the peripheral nerves

Which organic molecule has long hydrocarbon chains and is a major element of cell membranes?

  • A. Polypeptides
  • B. Carbohydrates
  • C. Phospholipids
  • D. Nucleotides
Correct Answer: C

Rationale: Phospholipids are the correct answer because they consist of long hydrocarbon chains and form the lipid bilayer, which is the fundamental structure of cell membranes. Their amphipathic nature (having both hydrophilic and hydrophobic regions) allows them to create a barrier that separates the cell's internal environment from the external environment, making them essential for cell integrity and function.

The nurse suspects that a patient will be diagnosed as being in a comatose state based upon the Glasgow Coma Scale score. What score does the patient need to have to be identified as comatose?

  • A. 7
  • B. 9
  • C. 11
  • D. 13
Correct Answer: A

Rationale: A GCS score of 7 or less indicates a comatose state, while a score of 15 indicates full alertness. Scores of 9, 11, and 13 suggest varying degrees of neurological impairment but not coma. Recognizing a comatose state is critical for patient management.
