ATI Practice Exam Pharmacology The Hematologic System Questions
Question 1 of 9
A client is admitted to the emergency room complaining of difficulty of breathing and upon auscultation, the nurse noted that the patient has wheezes. An allergic reaction to penicillin was
Correct Answer: D
Rationale: Albuterol (Ventolin HFA) is a short-acting beta-agonist bronchodilator commonly used to treat asthma exacerbations and wheezing. In this case, the patient presenting with wheezes and difficulty breathing likely has bronchospasm, which albuterol can help relieve by relaxing the muscles in the airways. It is the first-line treatment for acute bronchospasm and is administered via inhalation to provide quick relief of symptoms. Albuterol works rapidly to open up the airways, making it an appropriate initial medication to administer in this situation.
Question 2 of 9
The nurse teaches a class for college students about osteoporosis. What is the best information to include?
Correct Answer: A
Rationale: Osteoporosis prevention starts early-peak bone mass in 20s (diet, exercise)-per bone health science. Meds treat, not primarily prevent. It's not inevitable-lifestyle matters. Men get it too-less than women. Early action informs, per prevention.
Question 3 of 9
A 43-year-old Caucasian woman complains that her irises have been darkening. She says that she has been taking a drug for years to treat her glaucoma. Which of the following drugs is most likely causing the increased pigmentation of her irises?
Correct Answer: C
Rationale: Iris darkening in glaucoma treatment points to Latanoprost , a prostaglandin analog. It increases melanin in iridial melanocytes, a known side effect. Acetazolamide , a carbonic anhydrase inhibitor, Epinephrine , Pilocarpine , and Timolol (E) don't cause this. Latanoprost's cosmetic effect is well-documented, fitting her long-term use.
Question 4 of 9
A client is prescribed omeprazole (Prilosec) for GERD. Which instruction should the nurse include?
Correct Answer: A
Rationale: Omeprazole, a PPI, reduces acid by inhibiting proton pumps, most effective before meals when acid production peaks, optimizing GERD relief. With antacids reduces efficacy'PPIs need acidic pH. Crushing destroys enteric coating. Bedtime-only misses daytime acid. Pre-meal dosing aligns with omeprazole's mechanism, critical in GERD where timing enhances healing, making A the key instruction.
Question 5 of 9
What is the pharmacological class of Metformin?
Correct Answer: C
Rationale: Metformin belongs to the pharmacological class known as biguanides. Biguanides are a group of oral medications commonly used to treat type 2 diabetes by lowering blood sugar levels. Metformin works primarily by decreasing the production of glucose in the liver while also increasing the sensitivity of muscle cells to insulin. This class of drugs does not stimulate insulin release from the pancreas like sulfonylureas and meglitinides but rather works by targeting the liver and improving insulin sensitivity in peripheral tissues. The main pharmacological effect of metformin is to reduce hepatic glucose output, which helps to control blood glucose levels in individuals with type 2 diabetes.
Question 6 of 9
What is the classification of the drug Lithium?
Correct Answer: C
Rationale: Lithium is a mood stabilizer used primarily in the treatment of bipolar disorder. It helps to reduce the intensity and frequency of manic episodes in patients with bipolar disorder, as well as prevent the recurrence of both manic and depressive episodes. Lithium is not classified as an anti-diabetic, anti-ulcer agent, or diuretic.
Question 7 of 9
The physiologic differences in the pediatric patient compared with the adult patient affect the amount of drug needed to produce a therapeutic effect. The nurse is aware that one of the main differences is that infants have
Correct Answer: D
Rationale: Infants have a higher percentage of total body water (approximately 75%) compared to adults. This difference affects the distribution and concentration of water-soluble drugs, often requiring adjustments in dosing to achieve therapeutic effects. Increased protein in circulation, lower fat composition, and more muscular body composition are not primary factors influencing drug therapy in infants. Therefore, the nurse must consider the higher water composition when calculating drug dosages for pediatric patients.
Question 8 of 9
What is an expected outcome for Lithium
Correct Answer: D
Rationale: Lithium is commonly used in the treatment of bipolar disorder. One of the expected outcomes of lithium treatment is a decreased incidence of acute manic episodes. Lithium helps stabilize mood and reduce the frequency and severity of manic episodes in patients with bipolar disorder. It is considered one of the first-line treatments for managing symptoms of mania in bipolar disorder. While lithium has various physiological effects in the body, its primary use in mental health is to manage mood symptoms associated with bipolar disorder, particularly the manic phase. Therefore, the expected outcome of lithium treatment is a decrease in the incidence of acute manic episodes.
Question 9 of 9
A 64-year-old man is brought to the emergency department unconscious. He undergoes a CT of the chest, which reveals a pulmonary embolism. He is considered for immediate therapy with heparin. Because the man is unconscious, a history cannot be obtained from him. Which of the following would represent a contraindication to heparin therapy?
Correct Answer: D
Rationale: Heparin for pulmonary embolism has bleeding risks. Recent surgery -is a contraindication due to postoperative hemorrhage potential. Alcoholism , drug abuse , hypertension , and immune deficiency (E) aren't absolute. Surgery's timing is key in this unconscious patient.
