A nurse is preparing to administer phenylephrine to a client. The nurse should identify that which of the following manifestations is an adverse effect of this drug? Headache Sleepiness Hypotension Constipation

Headache Rationale: Oral sympathomimetics stimulate the adrenergic receptors, causing blood vessel constriction, which can cause nervousness, headache, blurred vision and tremors.

A nurse is teaching a client about albuterol. the nurse should instruct the client to monitor for and report which of the following as an adverse effect of this drug? Fever Bruising Polyuria Palpitations

Palpitations Rationale: Although not common at therapeutic doses, beta2 agonists can cause cardiac stimulation, resulting in chest pain, palpitations, hypertension, and arrhythmias.

A nurse should identify that dextromethorphan can have which of the following effects when combined with morphine? Reduces antitussive effect of dextromethorphan Potentiation of depression of CNS actions Increased renal reabsorption of the dextromethorphan Delayed analgesic effect of the opioid

Potentiation of depression of CNS actions Rationale: Potentiation of depression of VNS actions

A nurse is teaching a client about the use of antihistamines to treat allergic rhinitis. The nurse should explain that these drugs are effective because they perform which of the following actions? Decrease viscosity of nasal secretions Block H2 receptors Prevent histamine from binding to receptors Reduce nasal congestion

Prevent histamine from binding to receptors Rationale: Antihistamines treat allergic rhinitis and reduce swelling by blocking histamine from binding to the receptor sites.

A nurse is teaching a client about the use of cromolyn sodium to prevent bronchospasm. The nurse should explain that the drug has which of the following therapeutic effects? Increases leukocyte activity Blocks muscarinic receptors Causes bronchodilation Reduces Inflammation

Reduces inflammation Rationale: Cromolyn Sodium, a mast cell stabilizer, reduces inflammation by inhibiting the inflammatory response.

A nurse is teaching a client about the adverse effects of pseudoephedrine. Which of the following should the nurse include? Select all that apply Restlessness Bradycardia Insomnia Muscle Pain Anxiety

Restlessness Insomnia Anxiety Rationale: Restlessness is an adverse effect of pseudoephedrine, an oral sympathomimetic. Insomnia is an adverse effect of pseudoephedrine. Anxiety is an adverse effect of pseudoephedrine.

A nurse is teaching a client about montelukast. Which of the following instructions should the nurse include? Use a spacer to improve inhalation Take the drug at the onset of bronchospasm Rinse mouth to prevent oral fungal infection Take the drug once a day in the evening

Take the drug once a day in the evening Rationale: Montelukast, a leukotriene modifier, is most effective when taken once per day in the evening.

For which of the following reasons should a client attach a spacer to a metered dose inhaler? To increase the amount of drug delivered to the lungs To increase the amount of drug delivered to the oropharynx To increase the amount of drug delivered on exhalation To increase the speed of the drug delivery into the mouth

To increase the amount of drug delivered to the lungs Rationale: A spacer increases the amount of drug that reaches the lungs.

A nurse is teaching a client about the use of a mucolytic to treat a cough. The nurse should include that a mucolytic has which of the following therapeutic effects? Suppresses the cough stimulus Reduces inflammation Thins and Loosens mucus Dries secretions

Thins and loosens mucous Rationale: Mucolytics make mucus less viscous to increase a cough's productivity.

A nurse is teaching a client about ipratropium. Which of the following instructions should the nurse include? Do not drink anything 30minutes after using the drug Wait 5 min between using the drug and another inhaled drug This drug is used to thin respiratory secretions Check pulse rate after inhaling the drug

Wait 5 min between using the drug and another inhaled drug Rationale: Ipratropium, an inhaled anticholinergic, requires a 5-min wait between its administration and that of another inhaled drug to allow for bronchodilation to take effect.

A nurse is teaching a client about the use of an expectorant to treat a cough. The nurse should include that an expectorant has which of the following therapeutic effects? Suppresses the cough stimulus Reduces surface tension Reduces inflammation Dries mucous membranes

Reduces surface tension Rationale: Expectorants act by reducing the surface tension and viscosity of respiratory secretions. This results in thinning thick mucus, making it easier to cough out of the lungs and drain out of the nose and sinuses.
