A nurse is reviewing the medical record for a client who is at 38 weeks of gestation, tested positive for group B streptococcus B-hemolytic, and is allergic to penicillin. The nurse should identify that which of the following medications is contraindicated for this client?
Ampicillin
Erythromycin
Cefazolin
Clindamycin
The Correct Answer is A
Answer: A
Rationale:
A) Ampicillin: Ampicillin is contraindicated for this client because it belongs to the penicillin class of antibiotics. Since the client is allergic to penicillin, administering ampicillin could trigger an allergic reaction, which could range from mild rash to severe anaphylaxis.
B) Erythromycin: Erythromycin is a macrolide antibiotic and can be used as an alternative for clients who are allergic to penicillin. It is often prescribed for group B streptococcus infections in penicillin-allergic clients, making it a suitable option in this case.
C) Cefazolin: Cefazolin is a cephalosporin antibiotic and is generally considered safe for clients with a penicillin allergy, except in cases of severe penicillin allergies. Cross-reactivity is low, and cefazolin can be an appropriate choice for treating group B streptococcus.
D) Clindamycin: Clindamycin is a lincosamide antibiotic and is often used for clients with penicillin allergies. It is effective against group B streptococcus and does not belong to the penicillin or cephalosporin classes, making it a suitable option for this client.

Correct Answer is A
Explanation
A hemoglobin (Hgb) level of 8.8 mg/dL indicates anemia, which is a decrease in the oxygen-carrying capacity of the blood. Fatigue and tiredness are common symptoms of anemia. When the body does not have enough hemoglobin to transport oxygen effectively, it can lead to feelings of fatigue and a lack of energy.
The other options are not directly associated with a low hemoglobin level:
b) "I have noticed that my fingernails are becoming thicker." Thicker fingernails are not typically associated with a low hemoglobin level. Changes in fingernails can be atributed to various factors, but they are not directly related to anemia.
c) "I have to go to the bathroom all the time." Frequent urination is not typically associated with a low hemoglobin level. It can be related to other factors such as urinary tract infections, diabetes, or diuretic use, among others.
d) "I notice that my hands are always shaky." Hand tremors are not directly associated with a low hemoglobin level. Tremors can have various causes, such as neurological conditions, medication side effects, or excessive caffeine intake, but they are not directly linked to anemia.
Correct Answer is C
Explanation
A nurse collecting data from a client who reports having diarrhea for the past 3 days should identify that muscle weakness is a symptom of hypokalemia. Hypokalemia is a condition in which the blood potassium level is low and can be caused by excessive fluid loss through diarrhea. Potassium helps regulate muscle contractions, so when blood potassium levels are low, muscles may produce weaker contractions which result in muscle weakness.
The other options are not typical symptoms of hypokalemia.
a) Pitting edema is not a typical symptom of hypokalemia.
b) Diplopia is not a typical symptom of hypokalemia.
d) Hyperactive bowel sounds are not a typical symptom of hypokalemia.
