What action should the practical nurse (PN) instruct the client to perform prior to the instillation of nasal drops?
Use a tissue to clear the nose.
Inhale deeply through the nose.
Hold the breath temporarily.
Exhale deeply through the nose.
The Correct Answer is A
Choice A rationale
Clearing the nose with a tissue prior to the instillation of nasal drops can help to remove
mucus and other obstructions, allowing the medication to reach the nasal passages more
effectively15.
Choice B rationale
Deep inhalation through the nose is not typically recommended prior to the instillation of
nasal drops. It could potentially draw the medication deeper into the nasal passages or into the
throat, rather than allowing it to remain in the intended area15.
Choice C rationale
Holding the breath temporarily is not typically necessary or recommended prior to the
instillation of nasal drops15.
Choice D rationale
the nasal passages, but it is not as effective or recommended as using a tissue to clear the
nose15.

Correct Answer is B
Explanation
Choice A rationale
Montelukast does not increase the production of mucus in the lungs. In fact, it helps to reduce inflammation and may be used to prevent asthma attacks.
Choice B rationale
Montelukast is a leukotriene modifier that helps to reduce inflammation and prevent asthma attacks and exercise-induced bronchoconstriction. It works by blocking the action of leukotriene D4 in the lungs resulting in decreased inflammation and relaxation of smooth muscle. This prophylactic limitation of the inflammatory response to allergens is a key function of montelukast.
Choice C rationale
Montelukast does not contract the smooth muscles located in the respiratory tract. Instead, it helps to relax the smooth muscles in the lungs, reducing inflammation and making it easier to breathe.
Choice D rationale
Montelukast does not directly repair damaged tissue in the base of the lungs. Its primary function is to prevent and manage symptoms of asthma and allergies by reducing inflammation in the airways.
Correct Answer is B
Explanation
Choice A rationale
Pill-rolling hand motions are a common symptom of Parkinson’s disease. This is a type of tremor where the thumb and fingers rub together in a circular motion as if rolling a pill. This is not a contraindication to administering carbidopa-levodopa.
Choice B rationale
Anorexia, or loss of appetite, could be a sign of a more serious underlying condition or a side effect of the medication. This would require further assessment before administering the medication.
Choice C rationale
A flat affect, or reduced emotional expressiveness, is another common symptom of Parkinson’s disease. This would not typically require further assessment before administering carbidopa- levodopa.
Choice D rationale
Dizziness can be a side effect of carbidopa-levodopa. However, it would not typically require further assessment before administering the medication unless it was severe or persistent.
