A nurse is collecting data from a client who has pernicious anemia.
The nurse should identify that which of the following findings increases the client's risk for injury?

Wheezes: This finding may indicate a latex allergy, as wheezing is a sign of respiratory distress caused by an allergic reaction to latex proteins. Wheezes are not typical of malignant hyperthermia or hypovolemic shock.

Muscle rigidity: This finding is a hallmark of malignant hyperthermia, as it reflects the excessive calcium release and muscle contraction triggered by certain anesthetic agents. Muscle rigidity is not a feature of latex allergy or hypovolemic shock.

Urticaria: This finding is a common manifestation of latex allergy, as urticaria (hives) is a type of skin rash caused by an allergic reaction to latex proteins. Urticaria is not associated with malignant hyperthermia or hypovolemic shock.

Hypercapnia: This finding is indicative of malignant hyperthermia, as hypercapnia (high carbon dioxide levels in the blood) is a result of increased metabolism and oxygen consumption due to muscle rigidity and fever. Hypercapnia is not usually seen in latex allergy or hypovolemic shock, unless there is severe respiratory compromise.

Tachycardia: This finding can be present in all three disease processes, as tachycardia (fast heart rate) is a nonspecific response to stress, fever, pain, hypoxia, or hypovolemia. However, tachycardia is more pronounced and persistent in malignant hyperthermia and hypovolemic shock than in latex allergy.

Choice A rationale:

Tingling of the scalp. Tingling of the scalp is not a common adverse reaction following electroconvulsive therapy (ECT) ECT primarily affects the brain and may result in memory-related side effects, but tingling of the scalp is not typically associated with this procedure.

Choice C rationale:

Voice alteration. Voice alteration is not a common adverse reaction to ECT. ECT is a procedure that involves inducing controlled seizures in the brain, and its primary effects are on cognitive and neurological function rather than the vocal cords or voice.

Choice D rationale:

Neck pain. Neck pain is not a common adverse reaction to ECT. This procedure primarily affects the brain and central nervous system, and neck pain is not typically associated with it.

Choice B rationale:

Temporary memory loss. Temporary memory loss is a well-documented and common adverse reaction to electroconvulsive therapy (ECT) ECT can affect memory consolidation, and clients may experience temporary memory gaps or difficulties recalling recent events. However, these memory deficits are usually short-term and improve over time.
