Nokea
The physician prescribes decongestant intranasal spray. The nurse instructs the client on the proper use of the spray. Which of the following procedures is the CORRECT method?
- A. Finish instillation of spray into one nostril before spraying into the other nostril
- B. Inhale quickly to prevent irritation off the mucous membranes
- C. Blow the nose after spraying to prevent medications from entering the throat
- D. Tilt the head slightly forward and angle the bottle toward the side of the nostril
Correct Answer: D
Rationale: The correct answer is D: Tilt the head slightly forward and angle the bottle toward the side of the nostril. This method allows for proper administration of the spray into the nasal passage, ensuring effective delivery of the medication. Tilted head helps direct the spray towards the nasal cavity without causing discomfort or leakage. It also helps prevent the medication from dripping down the back of the throat.
Choices A, B, and C are incorrect:
A: Finishing instillation in one nostril before moving to the other can lead to uneven distribution of medication and reduced effectiveness.
B: Inhaling quickly may cause irritation and discomfort to the mucous membranes due to the forceful intake of the spray.
C: Blowing the nose after spraying can expel the medication before it has a chance to be absorbed, decreasing its efficacy.

Nurse Pedrito is teaching a client with Parkinson's disease on ways to prevent curvatures of the spine associated with the disease. To prevent spinal flexion, the nurse should tell the client to _________.
- A. Rest in supine position with his head elevated.
- B. Sleep only in dorsal recumbent position.
- C. Periodically lie in prone position without a neck pillow.
- D. Sleep on either side, but keep his back straight.
Correct Answer: C
Rationale: The correct answer is C: Periodically lie in prone position without a neck pillow. This position helps to prevent spinal flexion by promoting extension of the spine and stretching of the hip flexors. Prone positioning also helps maintain alignment of the spine and prevents contractures. Resting in supine position (choice A) with the head elevated does not promote spinal extension. Sleeping only in dorsal recumbent position (choice B) may lead to spinal flexion. Sleeping on either side (choice D) does not specifically address spinal flexion prevention.
Which of the following dental conditions is characterized by the wearing away of tooth structure due to friction from external sources such as toothbrushing or abrasive toothpaste?
- A. Dental caries
- B. Attrition
- C. Abrasion
- D. Erosion
Correct Answer: C
Rationale: The correct answer is C: Abrasion. Abrasion is the wearing away of tooth structure due to friction from external sources like toothbrushing or abrasive toothpaste. Dental caries (A) refers to tooth decay caused by bacteria. Attrition (B) is the wearing down of tooth structure due to tooth-to-tooth contact. Erosion (D) is the loss of tooth structure from acid attacks, not friction. Therefore, option C is the most fitting choice based on the description given.
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.
Outbreak of cases of typhoid fever occurs in the community. Nurse Keena should inform the residents that the transmission of the disease is through _______.
- A. A vector
- B. Blood and body fluids
- C. Food and water
- D. Air
Correct Answer: C
Rationale: The correct answer is C: Food and water. Typhoid fever is primarily transmitted through contaminated food and water by the bacterium Salmonella typhi. The bacteria are shed in the feces of infected individuals and can contaminate water sources or food prepared with contaminated water. This transmission route aligns with the typical epidemiology of typhoid fever outbreaks.
Now, let's discuss why the other choices are incorrect:
A: A vector - Typhoid fever is not transmitted by a vector such as mosquitoes or ticks.
B: Blood and body fluids - Typhoid fever is not typically spread through blood or body fluids but rather through ingestion of contaminated food or water.
D: Air - Typhoid fever is not an airborne disease and is not transmitted through the air.
A patient presents with excessive thirst, large volumes of dilute urine, and low urine osmolality. Laboratory tests reveal hypernatremia and elevated serum osmolality. Which endocrine disorder is most likely responsible for these symptoms?
- A. Hyperthyroidism
- B. Hypothyroidism
- C. Diabetes mellitus
- D. Diabetes insipidus
Correct Answer: D
Rationale: The correct answer is D: Diabetes insipidus. This condition is characterized by excessive thirst, large volumes of dilute urine, low urine osmolality, hypernatremia, and elevated serum osmolality. The underlying cause is a deficiency in or insensitivity to antidiuretic hormone (ADH), leading to the inability of the kidneys to concentrate urine properly. Hyperthyroidism (choice A) and hypothyroidism (choice B) do not directly affect urine concentration. While diabetes mellitus (choice C) can also present with polyuria and polydipsia, it would typically have high urine osmolality due to the presence of glucose. Therefore, diabetes insipidus is the most likely endocrine disorder responsible for these specific symptoms.
