Although there are no well-controlled studies in pregnant women, evidence we do have suggests there is no second or third trimester fetal risk. Animal studies reveal that these drugs can cause fetal harm in pregnancy. Thus this class of drugs should be avoided in during pregnancy. There is evidence that use of this drug class in pregnancy can harm the fetus so they should not be used. Systemic drugs in this class may cause birth defects, especially if taken during the first semester. If taken near term, the infant may develop kernicterus. Rationale: This information can be found in the Summary of Key Prescribing Considerations in the chapter that covers this drug class. Which patients being treated with a penicillin are at high risk for toxicity? (Select all that apply) renal impaired acutely ill Cephalosporins

CBC in patients with symptoms of blood disorders, CD4+ counts in patients with HIV and potassium 4 days after starting treatment in patients with possible hyperkalemia Penicillins Vancomycin Aminoglycosides Trimethoprim/Sulfamethoxazole Rationale: This information can be found in the Summary of Key Prescribing Considerations in the chapter that covers this drug class.

Levofloxacin Cefdinir Rationale: Nitrofurantoin can induce two kinds of pulmonary reactions: acute and subacute. Acute reactions, which are most common, manifest as dyspnea, chest pain, chills, fever, cough, and alveolar infiltrates. These symptoms resolve 2 to 4 days after discontinuing the drug. Acute pulmonary responses are thought to be hypersensitivity reactions. Patients with a history of these responses should not receive nitrofurantoin again. Subacute reactions are rare and occur during prolonged treatment. Symptoms (e.g., dyspnea, cough, malaise) usually regress over weeks to months after nitrofurantoin withdrawal. However, in some patients, permanent lung damage may occur. pg. 697 Which antibiotic classes should have a culture and sensitivity prior to prescribing and which ones do not according to your textbook? Culture Not indicated Rationale: This information can be found across the Summary of key prescribing considerations in the assigned reading chapters. Using your textbook, match the antibiotic class to the patient care concern for infants. Use each option only once by selecting the option that is most true.
