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
Hyponatremia refers to a lower-than-normal level of sodium in the blood. Sodium is an essential electrolyte involved in various bodily functions, including maintaining fluid balance and transmitting nerve impulses. When sodium levels are low, it can lead to fluid imbalances, affecting the function of muscles and nerves. Muscle cramps are a common manifestation of hyponatremia and occur due to alterations in muscle excitability and contractility.
Constipation: Constipation is not typically associated with hyponatremia. It can occur due to various reasons, such as dietary factors, lack of physical activity, or other medical conditions, but it is not a direct consequence of low sodium levels.
Hypertension: Hyponatremia is not usually associated with hypertension (high blood pressure). Hypertension can be caused by several factors, including genetics, lifestyle, and certain medical conditions, but it is not directly related to low sodium levels.
Blurred vision: While blurred vision can occur in some medical conditions, such as diabetes or certain eye disorders, it is not a typical finding in hyponatremia. Visual disturbances are not a direct consequence of low sodium levels.
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.
