Which of the following are clinical manifestations of anaphylaxis? select all that apply
Hypertension
Angioedema
Petechiae
Bronchospasm
Correct Answer : B,D
A. Hypertension: Anaphylaxis often leads to a rapid drop in blood pressure (hypotension) rather than hypertension. Hypotension is a more common symptom because of the severe vasodilation that occurs during anaphylactic reactions.
B. Angioedema: Yes, angioedema is a common clinical manifestation of anaphylaxis. Angioedema involves swelling of the deeper layers of the skin, often around the eyes and lips. It can also affect the throat, which can be life-threatening due to airway obstruction.
C. Petechiae: Petechiae are small red or purple spots that appear on the skin and are caused by bleeding into the skin's tissues. They are not a typical manifestation of anaphylaxis.
D. Bronchospasm: Yes, bronchospasm is a hallmark clinical manifestation of anaphylaxis. It involves the sudden constriction of the airways, leading to difficulty in breathing and wheezing.

Correct Answer is D
Explanation
A. Reddened tongue and gums: This side effect is not typically associated with ampicillin. However, certain medications or medical conditions can cause changes in oral tissues, leading to redness in the tongue and gums.
B. Digit numbness and tingling: Ampicillin does not commonly cause numbness and tingling in the fingers and toes. These symptoms can be associated with neurological issues or circulatory problems.
C. Bruising and petechiae: These symptoms can indicate bleeding disorders or low platelet count and are not usually caused by ampicillin. It's essential to investigate further if a patient experiences unexplained bruising or petechiae.
D. Skin rash and loose stools: Skin rash is a known side effect of penicillin-type antibiotics, including ampicillin. Loose stools or diarrhea can also occur due to disruption of the gut flora caused by the antibiotic. Patients should be aware of these possibilities and report any severe or persistent symptoms to their healthcare provider.
Correct Answer is B
Explanation
A. "Bactericidal and bacteriostatic are used interchangeably."
Explanation: This statement is incorrect. Bactericidal and bacteriostatic are two distinct categories of antibiotics with different mechanisms of action.
B. "Bactericidal drugs are directly lethal to bacteria, and bacteriostatic drugs work to slow bacterial growth but do not cause cell death."
Explanation: This statement is correct. Bactericidal drugs kill bacteria directly, leading to their death, while bacteriostatic drugs inhibit bacterial growth without causing immediate cell death.
C. "Bacteriostatic drugs are directly lethal to bacteria, and bactericidal drugs work to slow bacterial growth but do not cause cell death."
Explanation: This statement is incorrect. It is the opposite of the correct explanation. Bacteriostatic drugs do not directly kill bacteria, and bactericidal drugs do cause bacterial death.
D. "A bactericidal drug can cause death to the host, whereas a bacteriostatic drug only affects bacteria."
Explanation: This statement is not entirely accurate. While some bactericidal drugs can be more toxic to the host, it depends on the specific drug and its dosage. Bacteriostatic drugs, on the other hand, generally do not directly harm the host. The primary distinction between the two categories is their impact on bacterial growth and survival.
