Correct Answer: C

Rationale: The correct action the nurse should take when preparing to administer heparin subcutaneously is to administer the medication within 5 cm (2 in) of the umbilicus. This practice ensures proper subcutaneous delivery of the medication. Choice A is incorrect because a smaller gauge needle, typically 25-26 gauge, is used for subcutaneous injections. Choice B is incorrect as heparin should not be injected into the deltoid muscle but rather into fatty tissue. Choice D is incorrect as massaging the injection site after administration can lead to tissue irritation or bruising.

Correct Answer: A

Rationale: A hemoglobin level of 11.2 g/dL is below the normal range for a client who is 36 weeks gestation and should be reported to the provider.

Correct Answer: D

Rationale: A weight gain of 1 kg in 24 hours can indicate fluid retention and worsening heart failure, requiring an increase in diuresis. This finding suggests that the current diuretic therapy is not effective enough to manage the fluid overload, necessitating an increase in the infusion rate of furosemide. Choices A, B, and C are not directly related to the need for an increase in diuretic therapy in heart failure patients. Urine output of 20 mL/hr, a heart rate of 90/min, and a sodium level of 138 mEq/L are important parameters to monitor but do not specifically indicate the need to increase the infusion rate of furosemide.

Correct Answer: C

Rationale: The correct answer is C. Pacing spikes after the QRS complex indicate a malfunction of the pacemaker and should be reported. Choice A is not directly related to the pacemaker function. Choice B, hiccups, are common and not typically associated with pacemaker issues. Choice D, a heart rate of 90 beats per minute, is within the normal range and does not indicate a pacemaker malfunction.

Correct Answer: B

Rationale: The correct answer is to wear gloves to apply the patch to the client's skin. This action ensures that the nurse does not absorb any medication through their own skin, promoting safety. Choice A is incorrect because shaving is not necessary and could irritate the skin. Choice C is incorrect because transdermal patches should be applied immediately after removal from the protective pouch to maintain their efficacy. Choice D is incorrect because used patches should be folded and discarded safely according to facility protocols.
