Which instruction would the nurse least likely include in the teaching plan for a patient receiving an antitussive? a. Using a humidifier b. Limiting fluids c. Using lozenges d. Keeping the room cool
b. Limiting fluids (Rationale: Increased fluids are important to maintain hydration, thin secretions, and keep the mucous membranes moist. Humidification, cool temperatures, and lozenges are helpful in relieving cough.)
The physician ordered flunisolide for a patient who was previously prescribed ephedrine for seasonal rhinitis. What is the nurse's best response to the patient's question as to why his medication has been changed? a. "Patients who use flunisolide don't experience any adverse effects." b. "You aren't at any risk for infection with this medication." c. "Ephedrine is an old drug and flunisolide is a new drug." d. "Your physician has ordered your new medication because your previous medication wasn't giving you enough relief from your symptoms."
d. "Your physician has ordered your new medication because your previous medication wasn't giving you enough relief from your symptoms." (Rationale: Flunisolide is used as treatment for seasonal allergic rhinitis for patients who are not getting any response from other decongestant preparations. Ephedrine is an older product than flunisolide but flunisolide is prescribed because the ephedrine wasn't effective in treating the seasonal rhinitis. Patients who use flunisolide are at an increased risk for infection. Adverse effects with flunisolide include local burning, irritation, stinging, dryness of the mucosa, headache, and increased risk of infection.)

The nurse instructs a client who is prescribed a nasal steroid that it may take up to how long before effects may be noted?
7 days
A client prescribed codeine for a persistent, debilitating cough tells the nurse, "I was sure that codeine was a narcotic that people take for pain." The nurse should cite what mechanism of action when describing this use of codeine?
Depression of the cough center in the medulla oblongata
When instructing a patient in how to use a topical nasal spray, what would the nurse emphasize to do first? a. Lie down to tilt the head back. b. Spray the medication with the bottle upright. c. Clear the nasal passages. d. Close the opposite nares.
c. Clear the nasal passages. (Rationale: Before administering the nasal spray, it would be important to clear the nasal passages to ensure that the medication reaches its intended target, thereby promoting effectiveness. The bottle should be held upright but it is most important for the patient to clear the nasal passages before spraying the medication. It would be important for the patient to sit upright, not lie down. The patient should sit upright and press a finger over one nare to close it. After squeezing the medication, the procedure should be repeated with the opposite nare.)

"I should not drive my car after taking this medication."
Mr. Johnson is prescribed pseudoephedrine to relieve his nasal congestion. What should the nurse include in patient and family education? Select all that apply.
Advise him to avoid excessive and frequent use of the drug. Advise him not to take other OTC drugs.
Decongestants elicit their effect by which of the following mechanisms? (Choose one)
Vasoconstriction of small blood vessels of the nasal membranes Vasoconstriction of small blood vessels of the nasal membrane is the mechanism of action for decongestants. First-generation antihistamines act to nonselectively bind to peripheral H1 receptors; the mechanism of action for second-generation antihistamines is to selectively bind to peripheral H1 receptors; and peripherally acting antitussives anesthetize stretch receptors in the respiratory passages
The nurse is conducting a class for parents of newborns about the use of over-the-counter cough and cold medications. The nurse encourages the parents to follow which important safety information? (Select all that apply.) a. Do not give over-the-counter (OTC) medications to your child until he is older than 2 years. b. Do not give your child more than one cough and cold preparation at the same time. c. Carefully follow the directions in the "Drug Facts" section of the label. d. Cough and cold products can also be used to help your child go to sleep. e. Give your child half the adults dose if pediatric dosage instructions are not available.
a. Do not give over-the-counter (OTC) medications to your child until he is older than 2 years. b. Do not give your child more than one cough and cold preparation at the same time. c. Carefully follow the directions in the "Drug Facts" section of the label. (Rationale: Information that is important for parents includes: OTC medications for cough and cold should not be given to children under the age of 2, and extreme caution should be used if the child is age 2 to 6; do not give a child OTC cough and cold preparations unless they are labeled for pediatric use; always check the "Active Ingredients" on the drug label; do not give a child more than one cough and cold medication at the same time; follow the "Drug Facts" section of the label and follow the directions for how often the drug can be given; use the measuring spoons that come with the medication; always use child-proof caps; use the medication to treat only those symptoms that are affecting the child, and consult a doctor if the child's condition doesn't improve; do not use these products to help your child sleep; and tell the physician the names of any OTC products that the child is using.)
When describing the action of dornase alfa in treating cystic fibrosis, the nurse understands that this drug does what? a. Separates extracellular DNA from protein in mucus b. Binds with a metabolite that is toxic to the liver c. Splits the disulfide bonds that hold mucous material together d. Liquefies secretions to decrease viscosity
a. Separates extracellular DNA from protein in mucus (Rationale: Dornase alfa selectively breaks down respiratory tract mucus by separating extracellular DNA from proteins. Expectorants liquefy secretions. Acetylcysteine, in treating CF, splits apart the disulfide bonds that are responsible for holding the mucous material together. Acetylcysteine protects liver cells from damage because it normalizes hepatic glutathione levels and binds with a reactive hepatotoxic metabolite of acetaminophen.)
The nurse is caring for a patient who is receiving acetylcysteine by aerosol. The nurse is aware that this patient is at risk for what adverse effects? (Select all that apply.) a. Stomatitis b. Mucus plug c. Nasal congestion d. Nausea e. Bronchospasm
a. Stomatitis d. Nausea e. Bronchospasm (Rationale: Acetylcysteine is a mucolytic that is delivered by aerosol to help thin secretions. Adverse effects include nausea, stomatitis, urticaria, bronchospasm, and rhinorrhea. The patient would not be at risk for nasal congestion or mucus plug because the action of the medication is to thin secretions.)
When developing the teaching plan for a patient receiving an antihistamine, what would the nurse include? (Select all that apply.) a. Taking the drug on an empty stomach b. Encouraging the patient to engage in usual activities such as driving c. Reading the labels of OTC medications because they may contain the same ingredient d. Advising the patient to avoid alcohol consumption e. Using sugarless candies or lozenges to combat dry mouth f. Stopping the drug after 3 days if no relief is obtained
a. Taking the drug on an empty stomach c. Reading the labels of OTC medications because they may contain the same ingredient d. Advising the patient to avoid alcohol consumption e. Using sugarless candies or lozenges to combat dry mouth (Rationale: When taking an antihistamine, the nurse needs to inform the patient to take the drug on an empty stomach, 1 hour before or 2 hours after meals, use sugarless candies to combat dry mouth, to read the labels of OTC medications because they may contain the same ingredient or alcohol, which could increase the risk of adverse effects or toxicity, and to avoid alcohol intake to prevent excess CNS effects. The patient should not drive because of the sedation that occurs with antihistamines. The patient should not stop the medication without the physician's approval.)
Additional nursing interventions for clients receiving antihistamines would probably include which recommendations? a. Using a humidifier b. Advising the client to suck sugarless lozenges to help relieve the dry mouth c. Limiting fluid intake to decrease swelling d. Providing safety measures to prevent falls or injury e. Encouraging pushing fluids, if allowed f. Leaving bowls of water around the house to increase humidity
a. Using a humidifier b. Advising the client to suck sugarless lozenges to help relieve the dry mouth d. Providing safety measures to prevent falls or injury e. Encouraging pushing fluids, if allowed f. Leaving bowls of water around the house to increase humidity
The home health nurse is caring for an 83-year-old patient who has an upper respiratory infection and is taking an over-the-counter (OTC) cough and cold preparation. What issues must be discussed with this patient related to the OTC medication? (Select all that apply.) a. The patient may need an increased dose because of hepatic or renal impairment. b. The patient is at an increased risk for falls because of dizziness. c. The patient should expect to take the cough and cold medication for at least 2 to 3 weeks. d. The patient may become confused and disoriented. e. This patient should call the physician before taking this medication because it may be contraindicated due to other conditions the patient has.
b. The patient is at an increased risk for falls because of dizziness. d. The patient may become confused and disoriented. e. This patient should call the physician before taking this medication because it may be contraindicated due to other conditions the patient has. (Rationale: Older adults are more likely to develop adverse effects associated with the use of these drugs, including sedation, confusion, and dizziness. Older adults are also more likely to have renal and/or hepatic impairment related to underlying medical conditions. The does for older adults should be started at a lower level than recommended for younger adults and should be monitored very closely, with dose adjustment based on the patient's response.)
A patient who has been using a nasal decongestant for the last two weeks calls the clinic and asks for an antibiotic because the nasal congestion is getting worse instead of better. The nurse is aware that the patient has developed what condition? a. Vasoconstriction of the nasal capillaries b. Pneumonia c. Rhinitis medicamentosa d. Common cold
c. Rhinitis medicamentosa (Rationale: Rhinitis medicamentosa is rebound vasodilation caused by frequent or prolonged use of decongestants. The patient is experiencing vasodilation, not vasoconstriction of the nasal capillaries. The nasal congestion that the patient is experiencing is due to the rebound nasal congestion caused by the prolonged use of a topical nasal decongestant and does not have a cold. Patients with pneumonia have fever and cough and productive sputum. This patient is complaining of persistent nasal congestion caused by prolonged use of a topical nasal decongestant.)
The nurse is teaching a patient how to self-administer a medication that is contained in a nasal aerosol. The nurse knows the patient needs further instruction if she tells the nurse what information? (Select all that apply.) a. "I will press the canister and sniff twice and then blow out through my nose." b. "I will shake the medication well before using it." c. "I will blow my nose right before and right after I use the nasal aerosol." d. "I will lie down on the couch when I use this medication." e. "Just the tip of the applicator should be place inside my nostril."
a. "I will press the canister and sniff twice and then blow out through my nose." c. "I will blow my nose right before and right after I use the nasal aerosol." d. "I will lie down on the couch when I use this medication." (Rationale: The patient should place the medication cartridge into the plastic nasal adapter and shake it well. The tip of the applicator should be placed inside the nostril. The patient should sit upright and tilt the head back, then firmly press on the canister once to deliver the drug; the patient inhales, holds his breath for a few seconds, then exhales. The patient should keep the head tilted back for a few minutes and should not blow the nose for at least 2 minutes after the medication delivery.)
A client asks the nurse how long he should use oxymetazoline (Afrin) nasal spray for nasal congestion. What is the nurse's best response?
"Consult with your primary care provider." Overuse of topical nasal decongestants, such as Afrin, can make the symptoms worse, causing rebound congestion. The client should consult with the primary care provider.
A patient is advised to take a decongestant drug to relieve nasal congestion associated with hay fever. The patient is not comfortable with a nasal spray or drops and prefers an oral tablet. Which oral decongestant drugs can be administered to the patient?

The client states that he/she once needed medication to liquefy secretions in the respiratory tract. However, the client cannot recall the name of the medication but states that the medication is added to a nebulizer. The nurse suspects the client is taking which medication?
acetylcysteine
A patient calls the nurse help line and asks if he may take an over-the-counter (OTC) expectorant. The nurse is aware that an expectorant would be contraindicated or used very cautiously if the patient has what conditions? (Select all that apply.) a. Urinary tract infection b. Emphysema c. Hypothyroidism d. Very productive cough e. Asthma
b. Emphysema d. Very productive cough e. Asthma (Rationale: Possible contraindications or cautions include any history of allergy to the drug, persistent cough due to smoking, asthma or emphysema, or a very productive cough that would indicate an underlying problem that should be evaluated. Hypothyroidism and a urinary tract infection would not be contraindications for use of an expectorant.)
