Pharmacology Quiz 2 NU 160

Correct Answer B: Inspect your mouth for lesions daily.

Explanation of the Correct Answer:

Fluticasone is an inhaled corticosteroid (ICS) used for the long-term control of chronic obstructive pulmonary disease (COPD) and asthma. It helps reduce inflammation in the airways, making breathing easier over time.

One of the potential side effects of inhaled corticosteroids like fluticasone is the development of oral thrush, which is a fungal infection that can cause lesions in the mouth. It is important for the client to inspect their mouth daily for any signs of white patches, sores, or irritation. If these symptoms occur, the client should report them to their healthcare provider, as they may need treatment with antifungal medication. Rinsing the mouth with water after using the inhaler can help prevent this side effect.

Why the Other Options Are Incorrect:

A. Skip the morning dose if you do not have any symptoms. 

This is not a recommended instruction. Fluticasone is a maintenance medication used regularly to control inflammation and symptoms over time. Even if the client does not have symptoms, it is important to use the medication as prescribed. Skipping doses could reduce its effectiveness in managing the condition.

C. Use this medication to relieve an asthma attack.

This is incorrect. Fluticasone is a preventive medication, not a rescue medication. It does not provide immediate relief during an asthma attack. For acute attacks, the client should use a short-acting beta-agonist (SABA), such as albuterol, which works quickly to open the airways.

D. Check your heart rate before each dose.

Checking the heart rate is not typically necessary for fluticasone use. Fluticasone does not have significant effects on heart rate. However, if the client is taking other medications that could affect the heart rate (such as certain bronchodilators), they might need to monitor their heart rate, but it is not required for fluticasone itself.

Summary:

The correct instruction is B because oral thrush is a common side effect of inhaled corticosteroids like fluticasone. Checking the mouth for lesions daily helps detect and prevent this issue early.

Correct Answer:

A. Calcium carbonate

E. Aluminum hydroxide

Explanation of the Correct Answers:

A. Calcium carbonate:

Calcium carbonate is a common antacid used to relieve symptoms of heartburn or indigestion. One of its side effects is constipation. Calcium can reduce the motility of the gastrointestinal tract, leading to slower bowel movements. This is especially notable in individuals who take high doses of calcium carbonate, such as those using it as a calcium supplement or frequently for acid reflux.

E. Aluminum hydroxide:

Aluminum hydroxide, often found in antacids like Maalox and Mylanta, can also cause constipation. It has a tendency to slow down the passage of stool through the intestines. This is one of the reasons that aluminum-based antacids are sometimes combined with magnesium-based ones to balance their side effects.

Why the Other Options Are Incorrect:

B. Magnesium oxide:

Magnesium oxide is used for its antacid properties but is more likely to cause diarrhea, not constipation. Magnesium salts, in general, have a laxative effect and can promote bowel movements. Therefore, magnesium oxide is not associated with constipation.

C. Magnesium hydroxide:

Like magnesium oxide, magnesium hydroxide is known for its laxative effect. It works by drawing water into the intestines to stimulate bowel movements. It is commonly used in over-the-counter medications like Milk of Magnesia, and constipation is not a typical side effect.

D. Sodium bicarbonate:

Sodium bicarbonate, commonly known as baking soda, is used to neutralize stomach acid and can temporarily relieve heartburn. It does not typically cause constipation. In fact, it is more likely to cause symptoms like belching or bloating due to the release of carbon dioxide. It does not slow down bowel movements in the way calcium or aluminum-based antacids do.

Summary:

The antacids that can cause constipation are calcium carbonate and aluminum hydroxide. Both of these medications can slow gastrointestinal motility, leading to fewer bowel movements. Magnesium-based antacids, on the other hand, typically cause diarrhea, while sodium bicarbonate does not usually affect bowel movements.

Correct Answer C: Reduced dyspepsia

Explanation of the Correct Answer:

Omeprazole is a proton pump inhibitor (PPI) that works by reducing gastric acid production. It is commonly prescribed to treat conditions like gastroesophageal reflux disease (GERD), peptic ulcers, and dyspepsia (indigestion). Reduced dyspepsia—which includes symptoms like heartburn, bloating, and discomfort after eating—is a clear indication that omeprazole is effective in decreasing gastric acid secretion and improving the client's symptoms.

Why the Other Options Are Incorrect:

A. Regular bowel movements

Incorrect. Omeprazole does not directly affect bowel movements. While it may help with stomach acid, it is not intended to regulate bowel function.

B. Increased appetite

Incorrect. Omeprazole does not typically cause increased appetite. If a client experiences changes in appetite, other factors should be considered, such as medication side effects or underlying conditions.

D. Absence of headache

Incorrect. Headaches are not a primary symptom of the conditions that omeprazole treats, and the absence of a headache is not a direct indicator of the medication's effectiveness.

Summary:

The most appropriate indicator of omeprazole's effectiveness in this case is reduced dyspepsia, as the drug is designed to alleviate symptoms related to excessive stomach acid.

Correct Answer C: Renal stones

Explanation of the Correct Answer:

Calcium supplements are commonly prescribed for clients with osteoporosis to support bone mineral density and reduce fracture risk. However, one of the known adverse effects of calcium supplementation—particularly in high doses or when combined with inadequate fluid intake—is the development of renal (kidney) stones. These stones typically form when there is an excess of calcium excreted into the urine (hypercalciuria), leading to crystallization and the eventual formation of calcium oxalate or calcium phosphate stones.

The hallmark symptom of renal stones is flank pain, which can be severe, sharp, and radiating toward the lower abdomen or groin, depending on the stone’s location within the urinary tract. Clients may also report associated symptoms such as hematuria, nausea, vomiting, or dysuria. This presentation should prompt the nurse to suspect nephrolithiasis as a possible complication of calcium supplementation.

Why the Other Options Are Incorrect:

A. Hepatitis

Incorrect. Hepatitis involves inflammation of the liver and is not associated with calcium supplementation. It typically presents with right upper quadrant abdominal pain, jaundice, and abnormal liver function tests, not flank pain.

B. Hip fracture

Incorrect. Hip fractures are a complication of osteoporosis itself and not a result of taking calcium. In fact, calcium supplementation is intended to help prevent fractures. Additionally, hip fractures would present with localized hip or groin pain, not flank pain.

D. Pancreatitis

Incorrect. While extremely high levels of calcium (as seen in hyperparathyroidism) can rarely trigger pancreatitis, this is not a common side effect of calcium supplements alone. Pancreatitis is characterized by epigastric pain that may radiate to the back, not flank pain, making this an unlikely explanation in this case.

Summary:

The client’s report of flank pain while taking a daily calcium supplement is most consistent with renal stones, a known adverse effect of calcium supplementation due to its potential to increase urinary calcium and promote stone formation

Correct Answer D: I have an increased risk of getting pneumonia while taking this medication.

Explanation of the Correct Answer:

Esomeprazole is a proton pump inhibitor (PPI) used to reduce gastric acid production, commonly prescribed for gastroesophageal reflux disease (GERD), peptic ulcers, and other acid-related conditions. While effective, long-term use of PPIs like esomeprazole can lead to several adverse effects, one of which is an increased risk of pneumonia.

PPIs reduce the acidity of the stomach, which diminishes the natural defense against ingested pathogens. With less acid to kill bacteria, organisms can more easily travel to the respiratory tract, especially in older adults or hospitalized patients, increasing the risk of community-acquired or aspiration pneumonia.

Why the Other Options Are Incorrect:

A. I won’t pass gas as often now that I am taking this medication.

Incorrect. Esomeprazole may help reduce bloating or indigestion in some cases, but passing gas (flatulence) is not a specific target or guaranteed effect of this medication.

B. I will need to take a daily stool softener while taking this medication.

Incorrect. While constipation may occur in some individuals, it is not common enough to justify routine stool softener use unless prescribed. Patients should manage bowel changes based on symptoms.

C. I will take this medication each morning with my breakfast.

Incorrect. Esomeprazole should be taken at least 1 hour before a meal, typically in the morning, on an empty stomach, for maximum effectiveness. Taking it with food can reduce absorption.

Summary:

The statement that best shows understanding is D, recognizing that esomeprazole increases the risk of pneumonia, which is a known and important potential side effect of long-term PPI use.

Correct Answer C: Isoniazid can cause tingling of the hands.

Explanation of the Correct Answer:

C. Isoniazid can cause tingling of the hands.

Isoniazid is an antibiotic used to treat tuberculosis (TB), and one of its known adverse effects is peripheral neuropathy, which causes tingling, numbness, or a "pins and needles" sensation in the hands and feet. This is a result of nerve damage, often due to the drug’s effects on vitamin B6 (pyridoxine) metabolism. Patients on isoniazid are sometimes given vitamin B6 supplements to help prevent this side effect.

Why the Other Options Are Incorrect:

A. Isoniazid can cause ringing in the ears.

Ringing in the ears, or tinnitus, is not a typical side effect of isoniazid. It is more commonly associated with ototoxic drugs, like certain antibiotics (e.g., aminoglycosides) or chemotherapy agents, but not isoniazid.

B. Isoniazid can cause pain in the joints.

While joint pain is not a common adverse effect of isoniazid, it may rarely cause arthralgia (joint pain). However, this is not one of the main or characteristic side effects of the drug.

D. Isoniazid can cause yellowing of the skin.

Yellowing of the skin (jaundice) is more often related to liver dysfunction. While isoniazid can affect liver function (causing hepatotoxicity), it typically causes elevated liver enzymes, but yellowing of the skin is not a typical presentation. Jaundice may occur in severe liver toxicity, but it’s not a direct or common adverse effect of isoniazid alone.

Summary:

The correct answer is C because tingling in the hands (peripheral neuropathy) is a known adverse effect of isoniazid. Other side effects, such as pain in the joints, tinnitus, and jaundice, are not typical for this drug, although liver toxicity (which can lead to jaundice) is a known, though less frequent, serious side effect.

Correct Answer C: Dry mouth

Explanation of the Correct Answer:

Ipratropium is an anticholinergic medication commonly used in the management of chronic obstructive pulmonary disease (COPD) and asthma. A common side effect of anticholinergic medications, including ipratropium, is dry mouth. This occurs due to the inhibition of acetylcholine, which reduces salivation. Clients should be informed that this is a typical and manageable side effect.

Why the Other Options Are Incorrect:

A. Drowsiness

Incorrect. Ipratropium is not known to cause drowsiness. It is a bronchodilator and does not have sedative effects, which makes drowsiness an uncommon side effect.

B. Muscle tremors

Incorrect. Muscle tremors are more commonly associated with medications like beta-agonists (e.g., albuterol), not ipratropium. Ipratropium does not typically cause muscle tremors.

D. Increased salivation

Incorrect. Ipratropium works by blocking acetylcholine, leading to a decrease in salivation, not an increase. Increased salivation is not a side effect of ipratropium.

Summary:

The nurse should inform the client that dry mouth is a common side effect of ipratropium and advise the client on ways to manage it, such as drinking water or using sugar-free gum or lozenges.

Correct Answer:

A. Jaw pain

B. Tinnitus

C. Blurred vision

D. Dysphagia

Explanation of the Correct Answers:

A. Jaw pain:

Jaw pain is a serious side effect associated with bisphosphonates like alendronate, particularly because it can be a sign of osteonecrosis of the jaw. This condition is a rare but severe complication that can result from bisphosphonate therapy and requires prompt medical attention.

B. Tinnitus:

Tinnitus (ringing in the ears) is a possible side effect of alendronate, though it is not very common. It could indicate an issue with the medication and should be reported to the healthcare provider.

C. Blurred vision:

Blurred vision can be a sign of ocular toxicity, which, although rare, is a potential adverse effect of alendronate. If the client experiences any vision changes, it should be reported to the provider.

D. Dysphagia:

Dysphagia (difficulty swallowing) is a known side effect of bisphosphonates like alendronate, especially if the medication is not taken with sufficient water or the client lies down shortly after taking it. Difficulty swallowing could lead to esophageal irritation or even ulceration, so it is important to report this to the provider.

Why the Other Option Is Incorrect:E. Drowsiness:

Drowsiness is not a common or serious side effect of alendronate. It is not typically associated with the medication, and unless the client experiences extreme fatigue or unusual symptoms, drowsiness does not need to be reported.

Summary:

The nurse should instruct the client to report jaw pain, tinnitus, blurred vision, and dysphagia as these can indicate serious adverse effects like osteonecrosis of the jaw, ocular toxicity, or esophageal irritation. Drowsiness is not a typical side effect of alendronate and does not require immediate attention unless other symptoms develop.

Correct Answer D: Avoid driving until effects are known.

Explanation of the Correct Answer:

Cyclobenzaprine is a centrally acting skeletal muscle relaxant commonly prescribed to treat acute muscle spasms associated with musculoskeletal conditions. It works by depressing motor activity primarily in the brainstem, leading to muscle relaxation. One of the most important safety considerations when starting cyclobenzaprine is its sedative effect, which can cause drowsiness, dizziness, and impaired cognitive or motor performance.

Because of these central nervous system effects, clients are advised to avoid driving, operating heavy machinery, or engaging in hazardous activities until they understand how the drug affects them individually. This is particularly crucial during the initial stages of treatment or when the dose is increased, as sedation may be pronounced.

Why the Other Options Are Incorrect:

A. Monitor for increased muscle spasms

Incorrect. Cyclobenzaprine is used to reduce muscle spasms, not increase them. If spasms worsen, it may indicate an ineffective response, but it is not a common or expected adverse effect of the drug.

B. Discontinue medication if nausea occurs.

Incorrect. Nausea is a relatively mild and non-life-threatening side effect of cyclobenzaprine. It should not be a reason for abrupt discontinuation. Instead, clients should report persistent or severe nausea to their provider, who may adjust the dose or provide supportive measures.

C. Expect urine to turn orange

Incorrect. Orange discoloration of urine is associated with medications like phenazopyridine, not cyclobenzaprine. This is not an expected or typical side effect of this muscle relaxant.

Summary:

The nurse should teach the client to avoid driving until the effects of cyclobenzaprine are known, due to its potential to cause sedation and impair motor and cognitive function, especially during the initial treatment period.
